What are 6205 Bearings?
6205 bearings are compact deep groove ball bearings designed for radial loads and high speeds. They come in several variants like 6205-2RS (sealed), 6205-ZZ (shielded), and 6205-C3 (increased clearance). These bearings have a bore of 25mm, an outer diameter of 52mm, and a width of 15mm.
Types and Variants
The most common variants of 6205 Bearings include:
- 6205-2RS: Sealed on both sides with rubber seals to keep out dust and moisture. Dynamic load rating is 14.8 kN, static load rating is 6.55 kN.
- 6205-ZZ: Shielded bearings that use metal shields for protection against contaminants. These variants offer a dynamic load capacity of 13.9 kN and static load capacity of 7.2 kN.
- 6205-C3: Bearings with increased radial clearance to accommodate thermal expansion or installation ease. 6205 Bearings has the same dimensions but slightly different load ratings.
Materials and Specifications
6205 bearings typically use high-carbon chromium steel (AISI 52100) for the inner and outer rings, as well as ball components. The seals or shields are made from rubber or metal depending on the variant.
The rolling elements operate in a lubricant that reduces friction and wear. Sealed versions like 6205-2RS can handle temperatures up to 120°C, while shielded variants have a broader temperature range of -30°C to +120°C.
Selection Criteria
When choosing the right variant for your application:
- Load Requirements: Check if you need high dynamic or static load capacity. The sealed 6205-2RS handles higher loads than the shielded version.
- Environmental Conditions: For dusty or wet environments, opt for the 6205-2RS or similar sealed variants to protect against contaminants. If temperature extremes are a concern, choose shields over seals.
- Speed and Clearance Needs: Higher speed operations may favour increased clearance (C3) bearings due to reduced friction.
UK Suppliers
MLC lists verified suppliers from Companies House that stock 6205 Bearings. These include companies like MRP Engineering Ltd., which offers a wide range of bearing variants, including the popular 6205-2RS and 6205-ZZ types. Another supplier is The Bearing Centre UK Ltd., known for their competitive pricing and reliable delivery service.
Common Applications
These bearings find use in various industrial applications due to their compact size and performance capabilities:
- Industrial Machinery: Used in conveyor systems, pumps, and compressors.
- Automotive Industry: Found in steering gears, wheel hubs, and power transmission components.
- Agricultural Equipment: Suitable for tractors and harvesters where radial loads are common.
With these bearings, maintenance engineers can enhance the performance of equipment while reducing operational costs. Proper selection based on load requirements, environmental conditions, and speed constraints ensures longevity and efficiency in machinery.
