Specifications
Cylindrical roller bearings mostly consist of the cage, the rollers and guided by two capped edges on a ring. It can be classified into single row bearings such as NU, NJ, NUP, N, NF etc and other double row bearings such as NNU and NN. Single and double row full complement bearings (without cage) complete the standard assortment for general engineering.
Product Features and Benefits:
1) We offers a complete range, both metric and inch sizes available in metric and imperial bore sizes ranging from 20 to 1320 mm.
2) High radial load capacity - making them suitable for high speed applications.
3) Designs - designated NU, NJ, NUP, N or NF for single row bearings and NNU or NN for double row types, defines the bearing ring rib configuration.
4) Cages - Available with pressed steel, machined brass and polyamide cages throughout the range.
5)Special designs - We manufactures a range of four-row cylindrical roller bearings, primarily designed for use as steel mill roll-neck bearings.
6) Bearings are also available with both lubrication holes and a machined lubrication groove on the outside surface of the outer ring.
Models
Single row: N/NU/NJ/NF/NP/NUP/RN/RNU
Double row: NN/NNU/NNUP
Four row: FC/FCD/FCDP
Full complement: NCF/NNC/NNCF/NNCL/NNF/SL
DESIGN CLASSIFICATION
1. The roller and raceway are line contact. Great radial load rating capacity and can bear heavy load and impact load.
2. Small frictional factor. Suitable for high-speed. Its limiting speed is nearly the same as deep groove ball bearings
3. Inner ring and outer ring are separable which is favorable for assembly and disassembly.
CAGE CLASSIFICATION
1. EM double assembly machine process copper cage with outer ring or inner ring centered.
2. EM pressed steel cage with rollers centered.
3. EP-nylon cage with rollers centered.
PRODUCT ADVANTAGE OF TOWE
1. Improving cage design
2. Optimizing design of bearings ribs (can bear higher axial load)
3. Smaller tolerance of roller (average load is well distributed)
We can also according to your requirements to produce non-standard bearings
