The 62/28/25 2RS/C3 is a high-load non-standard deep groove ball bearing with exclusive metric dimensions of 25 mm × 58 mm × 16 mm (0.9843″ × 2.2835″ × 0.6299″) and a unit weight of 0.19kg. Unlike common standard 62-series bearings, this model features custom non-standard sizing, specially manufactured for industrial equipment, agricultural machinery and modified motors where off-the-shelf bearings cannot achieve precise fitting.

Equipped with2RS double rubber seals and C3 enlarged internal clearance, the bearing delivers full dustproof and waterproof performance, while adapting to high-speed continuous operation and elevated temperature environments. As a high-strength 62-series bearing solution, it solves the common industry pain point of “hard-to-find 25×58×16mm replacement bearings” and supports direct OEM replacement without equipment modification.

Technical Specifications

Why Does This Non-Standard Bearing Exist?

A widespread maintenance difficulty for engineers and equipment owners is the lack of standard bearings matching 25×58×16mm (0.9843×2.2835×0.6299 inch) dimensions. Many agricultural machines, drive motors and transmission devices adopt exclusive non-standard original bearing sizes that cannot be replaced by conventional 6200 series catalog bearings.

In most after-sales repair scenarios, technicians have to use improvised solutions, which lead to long-term equipment failures:

• Standard bearings fail to fit 25mm special shafts and 58mm bearing housings

• Relying on gaskets, spacers and sleeves for forced assembly

• Loose fit causes vibration, noise and eccentric operation

• High-speed operation generates heat and leads to bearing binding

• Reduced load-bearing capacity accelerates wear and failure

• Frequent replacement causes unplanned downtime and higher maintenance costs

The 62/28/25 2RS/C3 non-standard bearing is professionally developed to fill this exact size gap. It achieves 100% original dimension matching, requiring no shaft or housing modification, and restores equipment to factory-standard operating conditions.

Problems Solved by This Bearing

This exclusive 25×58×16mm (0.9843×2.2835×0.6299 inch) high-load bearing completely resolves common industrial sourcing and equipment problems:

• ✔ Hard-to-source 25×58×16mm obsolete and non-standard bearings

• ✔ Size mismatch when replacing original equipment bearings

• ✔ Performance degradation caused by modified assembly

• ✔ Vibration, overheating and noise during high-load operation

• ✔ Repeated maintenance and unstable equipment operation

• ✔ Long equipment downtime due to unavailable replacement parts

Core Engineering Advantages

1. 62-Series High-Load Structure

Compared with 60-series light-duty bearings, the 62-series features thicker steel walls and larger steel balls, providing stronger radial load capacity and impact resistance. It is more suitable for heavy-load, continuous-cycle industrial and agricultural equipment operation.

2. Exact Metric & Inch Zero-Modification Fit

Custom non-standard size (25×58×16mm / 0.9843″×2.2835″×0.6299″) fully matches original OEM installation parameters. No machining, no adapters, no spacers. It eliminates assembly gaps and ensures high-precision rotation stability.

3. 2RS Full Sealing for Harsh Environments

Double contact rubber seals effectively block dust, soil, moisture and splash water. It prevents grease leakage and internal contamination, perfectly adapting to outdoor farm environments, dusty workshops and open-type transmission equipment.

4. C3 Clearance for High-Speed & High-Temperature Resistance

C3 enlarged internal clearance reserves sufficient thermal expansion space. It avoids bearing jamming, overheating and premature failure during long-running motor and high-speed mechanical operation, delivering far better stability than standard C0 clearance bearings.

Cross Reference Equivalent Models

This 62/28/25 2RS/C3 non-standard bearing supports cross-brand replacement for aftermarket repair and OEM maintenance:

Note: Confirm dimensions and working conditions before cross-brand replacement.

Typical Applications

With high-load capacity, dustproof performance and high-speed stability, this non-standard bearing is widely used for hard-to-replace industrial and agricultural equipment:

• Industrial Drive Motors — C3 clearance adapts continuous high-speed and high-temperature operation

• Agricultural Machinery — 2RS sealing protects against field dust and moisture

• Transmission Gearboxes — 62-series high load capacity for heavy-duty operation

• Conveyor Systems — Stable performance for long-cycle industrial operation

• Modified & Special OEM Machinery — Exclusive size for non-standard equipment assembly

• Obsolete Bearing Replacement — Ideal solution for discontinued hard-to-find bearing models

Frequently Asked Questions

Q1: Can I use a standard bearing to replace 62/28/25 2RS/C3?A: No standard bearing matches the unique 25×58×16mm (0.9843×2.2835×0.6299 inch) size. Using modified standard bearings will cause loose fitting, vibration, overheating and reduced load capacity. Only this dedicated non-standard bearing guarantees stable high-load operation.

Q2: What makes this 62-series bearing different?A: It is a custom non-standard 62-series bearing. It retains the 62-series high-load advantage while solving the size gap that standard catalog bearings cannot cover, making it exclusive for special machinery and agricultural equipment.

Q3: Why is C3 clearance necessary for this model?A: This bearing runs continuously in motors and farm machinery. C3 clearance compensates for thermal expansion at high temperatures, preventing bearing tightness, friction overheating and premature failure.

Q4: Is the bearing pre-greased and ready to install?A: Yes. All units are factory pre-lubricated and fully sealed, ready for direct installation without extra maintenance.

Q5: Do you support small orders and customization?A: Yes. We support sample orders, small-batch maintenance orders and mass OEM production. Custom clearance, sealing and dimensions are available upon request.
