BN30-5TVVP4 Textile Machinery Bearing Φ30×Φ55×17 for Chunk Motor

Core application areas

‌Textile and chemical fiber equipment ‌

Mainly used for chemical fiber spindle, winding equipment, textile machine, etc., to support high-speed rotating parts and reduce friction ‌14.

Spindle bearing adopts single row short cylindrical roller structure without inner ring, which is suitable for high radial load and continuous operation ‌78.

‌High-end industrial scene ‌

Gradually expand to precision machine tools, industrial robots and other fields, the bearing accuracy and life requirements are higher ‌

Product technical characteristics

‌ High temperature resistance and high speed ‌

Some models, such as A-D25-1634 bearing with special material and structural design, can run stably in high temperature environment for more than 9000 hours ‌67.

Reinforced nylon cage (PA66 material) reduces roller swing, reduces noise and extends service life ‌78.

‌ precision manufacturing technology ‌

High precision deep groove raceway, optimized hole design to ensure rotation flexibility and stability ‌67.

Most of the imported products reach P5 level accuracy, suitable for precision chemical fiber equipment ‌25.

Installation and maintenance points

‌ Assembly requirements ‌

It is necessary to ensure the size of the inner hole of the bearing seat and the accuracy of the shoulder stop to avoid the life loss caused by the deformation of the outer ring or the tilt of the roller ‌47.

Complete sets of bearings need to be pre-selected to avoid direct replacement of spare parts affecting the performance ‌7.

‌ lubrication and maintenance ‌

Special anti-rust oil or grease (e.g. FAG K2N-30) is recommended for both rust protection and assembly stability ‌17.
