Ball Bearing Cartridges

Ball bearing cartridges are housings that mount ball bearings and stabilize shafts. They are made of rubber or metal and are typically round shaped. Ball bearing cartridges run quietly and dampen vibration.

Ball Insert Bearings

Ball insert bearings are housed in pillow blocks or flange mounts and secured onto shafts without complementary elements like shoulders or adapters. They can be slip fit directly onto the shaft without any special installation tools and then locked into place with set screws.

Bearing End Caps & Covers

Also called safety end caps, bearing end caps and covers fit over rotating shafts to protect moving parts and guard against hazards. Closed bearing covers completely encase the bearing, while open covers have an exposed center to allow access to the bearing. Closed and open bearing covers are typically made of plastic with metal fasteners.

Center Pull & Side Mount Take-Up Frames

Center pull and side mount take-up frames facilitate the movement of mounted housing bearing units. They are used primarily to align conveyor tracks and maintain conveyor belt tension. The mounted housing bearing unit houses the bearings that interact with the shaft going through the center. The assemblage then slides along the take-up frame as needed to align and maintain tension in the relevant component. This is done by means of a slot in the unit. In a center pull take-up frame, the adjustment pull axis is located in the center of the frame, guiding the bearing housing between the two sides of the frame. A side-mount frame is similarly configured but rests flat instead, allowing it to fit in tighter spaces. Take-up frames are used primarily for applications that use conveyor belts, such as fans and blowers, food processing equipment, and manufacturing and agriculture equipment.

Flange-Mount Ball Bearing Units

Flange-mount ball bearing units are used to accurately mount load supports when the mounting surface is perpendicular to the shaft axis. They consist of a housing that secures and positions a ball bearing. Flange-mount ball bearing units come in a diamond-shaped two-hole configuration, a circular three-hole configuration, and a square-shaped four-hole configuration that supports the highest radial loads.

Flange-Mount Roller Bearing Units

Flange-mount roller bearing units support heavy loads when the shaft axis is perpendicular to the mounting surface. They consist of a roller bearing installed in a flange mount. The roller bearing can have cylindrical, tapered, or spherical rolling elements. Flange mounts are typically round, square, or diamond shaped with two, three, or four mounting bolt holes. Four-bolt flange mounts support the heaviest loads.

Hanger Ball Bearing Units

Hanger ball bearing units reduce friction to provide an adjustable full-grip to vertical shafts. The bearing's rings and rolling elements are constantly loaded when the bearing is rotating. Hanger ball bearing units are used in commercial, industrial, and residential applications. They are available pre-lubricated, but lubrication can be easily reapplied for regular maintenance. Hanger ball bearings reduce vibration, ensuring a quiet operation.

Pillow Block Roller Bearing Units

Pillow block roller bearing units support loads of varying capacities from light- to heavy-duty applications. Pillow blocks house, secure, position, and protect the bearing while in use and have mounting holes for quick and adjustable mounting. Split housings come in two pieces for easier assembly, inspection, and bearing replacement. Different types of roller bearings are used in pillow blocks including needle roller bearings, cylindrical roller bearings, and tapered roller bearings.

Radial & Deep Groove Ball Bearings

Radial ball bearings handle radial loads effectively in high-speed operations. Also known as deep groove ball bearings, radial bearings are the most common type of rolling-element bearing. Deep, uninterrupted grooves in the raceway are manufactured with high precision to provide strong, consistent performance. Single-row radial ball bearings are non-separable. Double-row radial ball bearings reduce rotational friction in heavy-duty loads. Deep groove ball bearings may also handle light to moderate axial loads, also known as thrust loads. Stronger than shallow groove ball bearings, deep groove bearings require better alignment. Conrad and filling slot are the two main types of radial ball bearings. Also called non-fill slot, the Conrad design features a cage to prevent the bearings from moving. Filling slot bearings have notches between the inner and outer rings for maximum ball capacity, which allows them to carry greater radial loads. Filling slot bearings are also known as maximum capacity bearings or filling notch bearings.

Roller Insert Bearings

Roller insert bearings install into housings to carry heavier loads, support and stabilize shafts, and accommodate misalignment. They can have cylindrical, tapered, or spherical rolling elements that support heavy loads. Roller insert bearings require set screws and locking collars to securely lock the bearing into its housing.

Spherical Plain Bearings

Spherical plain bearings have an inner ring with a sphere that is convex on its outside and an inner ring with a concave sphere on its inside. This allows for oscillating at low speeds. They have a large contact area that can handle high radial and axial loads. Spherical plain bearings are also used in applications that involve mild misalignment, such as mining, construction, heavy movable structures, and miscellaneous vehicles.

Spherical Rod Ends

Spherical rod ends handle oscillating movement and angular misalignment in steering and pivoting applications. Also known as ball joint rod ends, spherical rod ends house spherical plain bearings. The rod end design supports pivoting within the housing to accommodate misalignment. Rod ends feature an eye-shaped head on a shank. Depending on the application, the shank may have male (external) or female (internal) threads. Left- and right-hand configurations are available for different operators. Metal or plastic may be used for the shank, housing, and inserts. Metal rod ends, often made of steel or bronze, are highly resistant to wear. These rod ends often require lubrication to ensure consistent, long working life with heavy loads. Many plastic rod end inserts are self-lubricating. Maintenance-free rod ends experience lower levels of friction and are ideal for light-duty applications.

Spherical Roller Bearings

Spherical roller bearings carry heavy radial loads and certain axial loads in both directions. They have spherical, barrel-shaped rollers and are self-aligning to handle shaft misalignment and mounting problems. Spherical roller bearings contain two rings on the inner raceway, which house the rollers, and one sphered outer ring. Spherical roller bearings work similarly to self-aligning double-row ball bearings but can accommodate heavier loads. Most spherical roller bearings contain a steel or brass cage. These materials are used for their strength, durability, and resistance to a variety of environmental factors. Raceway, cage, and roller designs affect the performance of spherical roller bearings.

Take-Up Ball Bearing Units

Take-up ball bearing units consist of a positioning screw and either top or side mounting hardware. Their wide inner ring allows for shaft alignment and belt tensioning. Take-up bearing units are used in a range of applications including conveyer belts, fans and blowers, and food processing plants. Different frame types are available, with some units featuring a locking collar. Heavy-duty take-up bearing units are typically made of cast iron while others are made of steel for light-duty applications.

Take-Up Bearing & Frame Assemblies

Take-up bearing assemblies align conveyor tracks and adjust and maintain tension on conveyor belts. These assemblies contain a bearing, housing, guiding frame, and positioning screw. The positioning screw adjusts the bearing and housing's location along the frame. This frame must be long enough to achieve proper tension in the belt. Take-up frames can be center-pull, top-pull, or bottom-pull depending on the positioning screw's location in the assembly. Frames guide the take-up bearing while the bearing reduces friction.

Penetrants & Multipurpose Lubricants

Penetrants and multipurpose lubricants prevent wear and friction and offer general purpose lubrication of machinery, components, and parts. Choose these products according to application, like high temperature, extreme temperature, and high pressure.
