KR72 stud type cam follower track roller bearing

Introduction

A cam follower is a type of bearing typically used to replicate a specific motion. In a cam and follower system, the cam is a mechanical element often in the form of a flat piece of metal tooled into an oblong shape that rotates or slides. The follower travels along the surface of the cam, tracking the shape by its edge and translating that shape into a movement pattern. The cam follower operates on a very simple principle and can be applied to a wide number of tasks, because although it is basic, it is also highly versatile. Cam follower systems are used in a wide variety of devices, including motor vehicles, moving lawn ornaments, and pumping devices.

Classification & Feature

Model KR, KR...PP Curve Roller
In Model KR, KR...PP curve roller, the rolling body is guided by cage and the outer is axially guided by the baffle ring on the bolt. It is suitable for heavy load and middle rotational speed. Since the bearing has a large grease-storage space, it has a long-term lubrication cycle. Model KR...PP curve roller has the contact-type seal structure.

Model KRV, KRV...PP Curve Roller
The structure of Model KRV, KRV...PP curve roller bearing is same with that of Model KR, KR...PP curve roller bearing. Model KRV, KRV...PP curve roller bearing is the full complement needle roller bearing. This cure roller bearing can withstand heavy load under the low speed. However it is necessary to add the lubricating Grease at regular intervals.

Model NUKR Cure Roller
Model NUKR cure roller bearing has the double-row roller structure. As same as parallel roller bearing, the outer ring is guided axially by rolling body. The cover pressed in outer ring and the shoulder constitutes the high-efficient gas seal. This kind of cure roller bearing can withstand the heavy load and the shock axial load because it is guided Axially by roller.

KRE KRE...PP Model KREV, KREV...PP NUKRE Curve Roller
Model KRE, KRE...PP, KREV, KREV...PP and NUKRE curve roller bearings are the special-purposed bearings in order to meet the supporting requirement of main machine. The outer ring has roller structure and the bolt shaft substitutes the inner ring. It has compact structure and can be equipped with eccentric-strap. The roller can be adjusted by means of the slot at end of bolt. The lubricating grease can be fed from both ends of Bolt.
