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.

HK

HK Series are open-type needle roller bearings with inner rings, featuring thin-walled rollers for high radial load capacity. Compact and space-saving, they suit gearboxes, motors, and automotive transmissions.

BK

BK series are drawn cup needle roller bearings with one closed end. They feature thin - walled outer rings and a high number of slender needle rollers, enabling high radial load capacity. Compact and space - saving, they're perfect for applications where space is limited, like small gearboxes and automotive parts.

TA TLA

TA/TLA series are needle roller bearings with cage and inner ring, featuring full complement rollers for high radial load capacity. TLA has a sealed design for dust prevention, suitable for motors, pumps, and industrial machinery.

TAM TLAM

TAM/TLAM series are needle roller bearings with inner ring and cage, designed for combined radial and axial loads. TLAM adds seals for contamination protection, ideal for heavy machinery, construction equipment, and gear reducers.

SCE BCE

SCE often comes with a drawn cup outer ring and may include a cage for roller guidance. BCE series usually features a closed - end drawn cup outer ring. Both offer high radial load capacity in a compact size, suitable for automotive transmissions, small motors, and machinery with space - constraint.

SCH

The SCH series are caged drawn shell cup needle roller bearings. They have a steel cage and thin - walled outer ring, made of high - carbon chromium steel. Suitable for high - speed and high - load applications with limited space.

BCH

BCH series are full complement needle roller bearings with a drawn cup outer ring and closed end. They feature high radial load capacity in compact designs, ideal for automotive gearboxes, pumps, and agricultural machinery.

BHA

The BHA series are shell - type needle roller bearings. They have a thin - walled outer ring made of special steel. There are caged and full - complement types. They can bear heavy loads and are suitable for various applications with space constraints.

BA

BA series are drawn cup needle roller bearings without inner ring. They feature a thin - walled outer ring and needle rollers directly contacting the shaft, ideal for space - saving, high - radial load applications like motors and gearboxes.

J JH

J JH series are caged needle roller bearings with an inner ring and flanged outer ring. They combine a steel cage, needle rollers, and a flanged outer ring for axial location, suitable for high - speed applications in machinery requiring compact design.

HF

HF series are needle roller bearings with a flanged outer ring and inner ring, often equipped with a cage. The flanged outer ring provides axial location, while the inner ring allows direct shaft contact. Suitable for applications requiring both radial and axial load support, such as conveyor systems and printing machinery.

HFL

HFL series are needle roller bearings with a flanged outer ring, inner ring, and extended inner ring design. The extended inner ring provides additional support for shafts, while the flanged outer ring offers axial positioning. Typically used in applications requiring high radial load capacity and precise axial guidance, such as automotive transmissions and industrial gear units.

F FH

F series are drawn cup needle roller bearings without inner ring, featuring a thin-walled outer ring and full-complement needle rollers (without cage). They are designed for high radial load capacity in space-constrained applications, where the shaft surface directly acts as the raceway.FH series are similar to F series but with a flanged outer ring, providing axial positioning while maintaining the inner ring-less design. The flange helps prevent axial displacement, making them suitable for applications requiring both radial load support and simple axial fixation.

MF MFH

MF series are needle roller bearings with an inner ring, thin-walled outer ring, and cage. They feature high radial load capacity in a compact design, suitable for applications where the shaft requires direct contact with the inner ring (e.g., motors and pumps).MFH series are variants of MF with a flanged outer ring, adding axial positioning capability. The flange eliminates the need for additional retaining components, ideal for gearboxes and conveyors requiring both radial support and axial fixation.

HK..RS 2RS

HK...RS/2RS are drawn cup full complement needle roller bearings with single/double seals. Thin-walled for space-saving, they resist high radial loads and protect against contaminants, suitable for auto transmissions and harsh environments.

BK..RS

BK..RS are drawn cup needle roller bearings with one closed end and single seal. Featuring high radial load capacity, they prevent contamination and suit space-constrained applications like gearboxes and motors.

KZK

KZK are needle roller bearings with cage, drawn cup outer ring, and open ends. Designed for high radial loads, they allow high-speed operation and suit precision machinery like textile equipment.

KBK

KBK are needle roller bearings with cage, drawn cup outer ring, and one closed end. Offering high radial load capacity, they prevent contamination and suit gearboxes or motors needing space-saving solutions.

IR

IR are needle roller bearings with inner ring, drawn cup outer ring, and open ends. Designed for high radial loads, they feature a separable design for easy installation, suitable for machinery requiring frequent maintenance.

IRT

IRT are needle roller bearings with inner ring, drawn cup outer ring, and one closed end. They combine high radial load capacity with contamination protection, suitable for gearboxes and motors in dusty environments.
