Roller Bearings

Roller bearings employ cylindrical or tapered rollers for higher radial load capacity than ball bearings. Suitable for heavy-duty applications like industrial machinery and automotive transmissions.

Needle Roller Bearings

Needle roller bearings feature cylindrical rollers with a length-to-diameter ratio of at least 4:1, enabling a compact design that fits in space-constrained applications. They have high radial load capacity due to the large contact area between rollers and raceways, while low friction coefficients reduce energy loss. Some types include integral seals to prevent contamination or locking mechanisms to secure the bearing on shafts/housings.

Spherical Roller Bearings

Spherical roller bearings have two rows of rollers and a spherical outer ring raceway, self-aligning to shaft misalignment. Ideal for heavy radial loads in motors, pumps, and conveyors.

Cylindrical Roller Bearings

Cylindrical roller bearings consist of inner/outer rings, cylindrical rollers, and cages, designed to handle heavy radial loads with minimal axial load capacity. Their linear contact between rollers and raceways ensures high rigidity and low friction, making them suitable for high-speed applications. Features like anti-corrosion coatings or self-lubricating materials can enhance durability in harsh environments.

Tapered Roller Bearings

Tapered roller bearings feature conical rollers and raceways that intersect at a common axis, enabling them to carry combined radial and axial loads in one direction. The contact angle determines axial load capacity—larger angles handle heavier thrust loads. They are often used in pairs to withstand bidirectional loads and are ideal for applications like vehicle wheel hubs, gearboxes, and heavy machinery requiring high load capacity and rigidity.

Split Roller Bearings

Split roller bearings feature separable inner/outer rings, allowing installation without shaft disassembly. Suitable for large motors, generators, and heavy machinery requiring easy maintenance.

CARB Toroidal Roller Bearings

CARB toroidal roller bearings feature toroidal outer ring raceways, combining self-aligning capability with axial displacement freedom. Ideal for paper machines, conveyors, and gear systems with shaft expansion.
