Description

SL045011 PP-2NR

Cylindrical Roller Bearing
Brand: NIS

Key Features

• Full Complement Roller Design
  Provides higher load capacity than caged bearings. Ideal for heavy-duty applications.

• Double Contact Seals (PP)
  Seals on both sides protect against dust and contamination, while retaining grease for longer service life.

• Snap Ring Grooves with Snap Rings (2NR)
  Simplifies axial positioning in housings without the need for additional components.

• Cage-less Construction
  Increases the number of rollers inside the bearing, improving load and shock resistance.

• Standard Radial Clearance (CN)
  Suitable for general-purpose applications without the need for high precision.

• Compact and Lightweight (0.25 kg)
  Easy to install and ideal for space-constrained environments.

Typical Applications

• Hydraulic Motors
  Efficiently handles both radial and axial loads.

• Heavy Industrial Machinery
  Such as presses, rolling machines, and injection molding machines.

• Gearboxes / Speed Reducers
  Ensures stable and continuous load transfer.

• Cranes and Lifting Equipment
  Provides excellent radial load-carrying performance.

• Construction and Mining Equipment
  Built to withstand harsh conditions including dust and moisture.

Installation and Usage Recommendations

• It is recommended to install using a press-fit method for optimal performance.

• Avoid direct impact or hammering on the bearing surfaces.

• Align the snap ring grooves accurately with the grooves in the housing.

• The bearing is pre-lubricated with grease from the factory and does not require additional greasing initially.
