Cylindrical Roller Bearings FAG NJ307 -E-XL-M1A-C3

The FAG NJ307 -E-XL-M1A-C3 cylindrical roller bearing, measuring 35 × 80 × 21 mm, can accommodate high radial loads as well as unilateral axial forces.

The NJ307 -E-XL-M1A-C3 cylindrical roller bearing is a single-row roller bearing from FAG designed for demanding industrial applications. Thanks to the line contact between the rollers and raceways, the design is capable of withstanding high radial forces. The NJ version features two fixed flanges on the outer ring and one fixed flange on the inner ring, making the bearing suitable for use as a support bearing. As this is an open bearing without an integrated seal, lubrication is provided by the surrounding system.

What is the NJ307 -E-XL-M1A-C3 cylindrical roller bearing suitable for as a support bearing?

This design is used when a bearing arrangement is required to accommodate radial loads and to guide a shaft axially in one direction. As the inner ring can be removed from one side, the shaft can be moved axially in one direction, whilst the opposite direction is supported by a positive fit. Typical applications include industrial drives and gearbox assemblies. The separable design also simplifies the separate installation of the inner and outer rings in the housing or on the shaft.

What properties do the solid brass cage and the C3 clearance offer?

The designation M1A denotes a solid brass cage with an external guide, which guides the rollers with dimensional stability even under vibration and varying speeds. The suffix C3 indicates a slightly increased radial bearing clearance. This increased clearance compensates for operational thermal expansion or tight fit allowances between the shaft and housing, thereby preventing the bearing assembly from becoming stressed. With tolerance class P0 (ABEC 1), the component complies with the standard precision requirements for industrial use.
