Product Overview
The 6205 2RS bearing is a single-row deep groove ball bearing with contact rubber seals on both sides, designed for the common 25 mm shaft class. It carries radial loads and moderate axial loads in both directions, while the sealed design locks in grease and keeps out dust, water and debris. That protection makes the 6205-2RS a first-choice replacement bearing for agricultural machinery, pumps, fans and conveyor drives that run in exposed conditions. Machined from chrome steel with a pressed steel cage, it offers quiet running and long, maintenance-free service. The 6205RS bearing interchanges directly with major brand equivalents and is available in standard and C3 clearance grades.

All dimensions and tolerances conform to ISO 492 and ISO 15 rolling bearing standards, ensuring interchangeability and consistent fit across global supply chains. This model is equivalent to the SKF 6205-2RS1 designation.
Features and Benefits
- Contact rubber seals on both sides — keeps grease in and blocks dust, water and debris, delivering longer service life with less maintenance.
- Deep groove raceway design — supports radial and moderate axial loads in both directions, one bearing covers most shaft load conditions.
- Chrome steel (GCr15) rings and balls — high hardness and dimensional stability, consistent performance under continuous operation.
- Pressed steel cage — quiet running with reliable ball guidance, low noise in motor and fan applications.
- ISO 15 boundary dimensions — matches major brand equivalents exactly, drop-in interchangeability for replacements.
Applications
Agricultural Machinery
Dust, vibration and outdoor moisture are the norm in farming equipment, and the sealed 6205 2RS bearing is specified to survive them with minimal maintenance.
- PTO shafts and mowers
- Balers and elevators
- Sprayers
- Grain handling equipment
Pumps & Compressors
The contact seals protect the bearing from process moisture and washdown water, which is why the 6205-2RS is a common service item in pump and compressor rebuilds.
- Centrifugal pumps
- Air compressors
- Irrigation systems
- Water treatment equipment
Conveyors & Fans
For medium-duty shafts in conveying and air-moving equipment, the 6205 2RS bearing gives dependable radial support at high volumes, and complements our other deep groove ball bearings in the 62 series range.
- Belt and roller conveyors
- Industrial fans
- Blowers and ventilators
- Machine tool feed units
Quality and Manufacturing
Each 6205 2RS bearing is manufactured from GCr15 chrome steel to ISO 492 P0 tolerance class. Rings and balls are ground to specification, and every bearing is inspected for radial internal clearance, running noise and seal integrity before it is packed and shipped.

Frequently Asked Questions
What are the dimensions of a 6205 2RS bearing?
A 6205 2RS bearing has a 25 mm bore, a 52 mm outside diameter and a 15 mm width (25×52×15 mm), with a 1 mm minimum chamfer and contact rubber seals on both sides.
What is the difference between a 6205 2RS and a 6205 ZZ bearing?
6205 2RS has rubber contact seals on both sides for maximum protection against contamination, while 6205 ZZ has metal shields for lower friction and higher speed capability. Sealed 2RS is the better choice for dirty or damp environments.
What is the load rating of a 6205 2RS bearing?
The basic dynamic load rating (Cr) is 14,000 N and the basic static load rating (C0r) is 7,800 N.
What is the limiting speed of a 6205 2RS bearing?
The limiting speed of the 6205 2RS bearing with grease lubrication is 8,500 rpm.
What is the weight of a 6205 2RS bearing?
The approximate mass of a 6205 2RS bearing is 0.128 kg.
What material are 6205 2RS bearings made of?
The rings and balls of the 6205 2RS bearing are made of GCr15 chrome bearing steel, with a pressed steel cage and rubber contact seals on both sides.
Is 6205RS the same as a 6205 2RS bearing?
Yes. 6205RS and 6205 2RS are alternative spellings of the same bearing — a 6205 deep groove ball bearing sealed on both sides. SKF designates it 6205-2RS1 and NSK designates it 6205DDU.
What does 2RS mean on a bearing?
2RS means the bearing has two rubber contact seals, one on each side. The seals keep grease inside the bearing and prevent dust, water and other contamination from entering.
Where is a 6205 2RS bearing commonly used?
Agricultural machinery, pumps, compressors, fans, conveyor systems and various industrial drives are the most common applications for the 6205 2RS bearing.
