Single Row Ball Bearing with Rubber Seal

LOCUS Single Row Ball Bearings with Rubber Seals are high-performance deep groove ball bearings designed for smooth rotation and durability. The rubber seals on one or both sides prevent contamination and retain lubrication, making them ideal for applications exposed to dust, moisture, or light chemicals.

Description

1. Product Description

2. Specifications

Inner and outer rings: AISI 52100 chrome steel
Balls: High precision steel balls
Seal: Nitrile Rubber Seals (RS or 2RS)
Cage: Steel cage / Nylon cage (optional)
Grease: High-speed, high-temperature lithium-based grease
Tolerance: ABEC 1 / P0 (Standard), optional ABEC 3 / P6

3. Working

The bearing operates by allowing smooth, low-friction rotation between two parts while supporting radial and limited axial loads. The rubber seal maintains lubrication and protects from environmental contaminants, enhancing life span.

4. Principle

Utilizes balls between inner and outer races to minimize rotational resistance. Rubber seals enhance performance by maintaining grease inside and preventing ingress of particles and moisture.

5. Assembly

Inner ring pressed onto the shaft
Outer ring fitted into the housing
Ensure proper alignment
Sealed units do not require additional sealing

6. Installation Process

Clean shaft and housing
Align the bearing with shaft
Press-fit bearing using proper tools
Do not hammer directly
Check axial and radial play
