Tapered Roller Thrust Bearings FAQS

QWhat is THE STRUCTURE OF THE TAPERED ROLLER THRUST BEARINGS?

ABecause the rolling body of the thrust tapered roller bearing is tapered roller, in structure, the rolling bus and the raceway bus of the washer converge at a certain point on the axis of the bearing, so the rolling surface can form pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing. Due to the small production of the thrust tapered roller bearing, most of the models that have been produced by various factories are non-standard Boundary dimensions, while the series of standard boundary dimensions have less variety production, so there is no national standard for the boundary dimensions of such bearings. At present, the available standard is GB / T 4663-1994.

QWhat are THE CHARACTERISTICS OF THE NEEDLE ROLLER THRUST BEARINGS?

AAble to bear axial heavy load and impact load In an assembly, the diameter deviation of the needle roller is very small, so that these bearings can bear heavy axial load and impact load. Prolong service life of bearing To prevent the peak stress, both ends of the needle slightly shrink to change the line contact between the raceway and the needle.

QWhat is PILLOW BLOCK?

AConventional bearing units include: One bearing with seat (y bearing), based on single row deep groove ball bearing, with a raised outer ring and an extended inner ring One bearing housing with a corresponding spherical concave hole

QWhat should be NOTICED ABOUT THE CAM FOLLOWERS?

A1. Advantages of cam mechanism By designing proper cam profile, the follower can get any desired movement, and its structure is simple, compact and convenient. Therefore, it is widely used in automatic machine tools, light industrial machinery, textile machinery, printing machinery, food machinery, packaging machinery and mechatronic products. 2. Disadvantages of cam mechanism 1) the contact between cam and follower is point or line, which is easy to wear, so it is only suitable for the occasion with small force transmission; 2) the accuracy of cam profile is required to be high, and it needs to be processed by numerical control machine. 3) the stroke of the follower shall not be too large, otherwise the cam will become heavy.
