FAQ Question?What is the proper mounting procedure for the UKP313D1 with its adapter sleeve? Answer:The UKP313D1 uses an H2313 adapter sleeve. To mount it, slide the unit onto the shaft, position the sleeve, and then tighten the locknut until the specified radial clearance reduction is achieved. It is crucial to use a hook spanner and follow NSK’s torque or turn-of-nut recommendations to prevent over-tightening, which can damage the bearing. Question?Can this bearing unit be relubricated, and what type of grease should be used? Answer:Yes, the P313 housing is equipped with a grease nipple for relubrication. NSK recommends using a high-quality lithium soap-based grease. The relubrication interval depends heavily on the operating conditions, such as speed, load, and environmental factors like dust and moisture. Question?What does the “UK” prefix in the bearing insert signify? Answer:The “UK” prefix denotes a bearing insert with a tapered bore designed for mounting with an adapter sleeve. This contrasts with “UC” type bearings, which have a cylindrical bore and are typically mounted using set screws. The adapter sleeve mounting of the UK series provides a more concentric and secure grip on the shaft, making it suitable for higher speeds and applications with vibration.
