6312-RS1 (CN) Bearing Product Overview & Core Advantages

The 6312-RS1 (CN) is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features an integrated RS1 contact seal that provides excellent protection against contamination while retaining lubrication. Engineered with chrome steel rings, balls, and cage, it offers robust radial load capacity and consistent operation. Its ABEC 1 | ISO P0 tolerance class ensures dependable precision for general industrial use, making it an ideal solution for applications requiring a balance of performance, protection, and value.

6312-RS1 (CN) Bearing Model Code Explained, Specifications & Naming Convention

Code Segment Technical Meaning Advantage
6312 Basic series code indicating a medium series, single row deep groove ball bearing with a 60 mm bore and 130 mm OD. Standardized dimensions for easy interchangeability and sourcing.
RS1 Denotes a contact seal made of Nitrile Rubber (NBR) on one side of the bearing. Provides effective protection from contaminants like dust and moisture. Helps retain grease, contributing to extended service life.
(CN) Suffix indicating a standard C3 radial internal clearance group. Suitable for applications where operational temperatures cause differential expansion between the inner and outer rings, preventing pre-load and ensuring smooth running.

6312-RS1 (CN) Bearing Structural Features & Performance Benefits

  • Robust Construction & High Load Capacity: Manufactured entirely from chrome steel, this bearing provides high strength and durability. With a dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, it is well-suited for significant radial loads.
  • Effective Sealing with RS1: The contact seal effectively shields the internal components from solid and liquid contaminants, making it ideal for dirty or humid environments. This design supports maintenance-free operation in many applications.
  • Optimized Internal Clearance: The standard C3 clearance provides greater internal space than a normal CN group. This is advantageous in applications with high thermal gradients, preventing binding and reducing friction and heat generation.
  • Wide Temperature Range: The bearing's construction and seal material allow for operation within a temperature range of -30°C to 120°C, accommodating various industrial conditions.

6312-RS1 (CN) Bearing Typical Application Areas

The 6312-RS1 (CN) is a versatile component found in a wide range of industrial machinery, including:

  • Electric Motors and Gearboxes
  • Industrial Fans and Blowers
  • Conveyor Systems
  • Agricultural Machinery
  • Material Handling Equipment

Its sealed and robust design makes it a preferred choice for applications where reliability and contamination protection are critical.
