⚙️Product Description:
The S6302-2RS (15x42x13mm, also designated as SS6302-2RS / S6302 2RS) is a heavy-series precision deep groove ball bearing engineered from high-grade AISI 420 martensitic stainless steel for superior rust resistance and load capacity. Featuring a 15mm inner bore, 42mm outer diameter, and 13mm width, its reinforced 6300-series cross-section accommodates significantly higher radial loads and moderate bilateral thrust forces than light-series bearings. Equipped with dual-lip NBR rubber seals (2RS) pre-filled with water-resistant grease, it prevents moisture ingress and saltwater pitting in severe marine, washdown, and chemical environments. We supply these corrosion-proof bearings under our proprietary RMO brand while facilitating flexible multi-brand OEM direct sourcing for marine machinery, bottling lines, and liquid processing equipment manufacturers.

⚙️Product Features:
- AISI 420 Martensitic Stainless Steel: High-carbon martensitic alloy provides excellent corrosion protection against fresh/salt water, mild acids, and damp air while maintaining outer ring hardness.
- Heavy-Duty 6302 Series Envelope: Thicker raceway rings and larger steel ball complement deliver high dynamic radial load ratings and shock resistance compared to 6002/6202 options.
- Dual-Lip Waterproof 2RS Seals: NBR rubber contact seals keep out water spray, grit, and harsh sanitizing detergents while retaining long-life synthetic grease.
- Low Friction & Smooth Velocity: Micro-honed raceways ensure low running noise, reduced temperature rise, and extended service life in high-humidity operating environments.
⚙️Product Application:
Engineered for severe marine exposure, high-pressure washdown cycles, and heavy radial loads, the S6302-2RS stainless ball bearing is widely specified in:
- Marine & nautical equipment: outboard motor propeller shafts, boat trailer wheel hubs, marine winches, and saltwater pumps.
- Food & beverage automation: commercial meat grinders, dairy bottling line drives, brewery pumps, and conveyor rollers.
- Chemical & fluid handling: chemical metering pumps, swimming pool filtration systems, and water treatment agitators.
- Car wash & cleaning systems: automatic car wash brush rotators, pressure washer pumps, and industrial floor scrubbers.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
