Product Introduction

The 6003‑RS is a widely‑used single‑row deep groove ball bearing with single‑sided rubber contact seal, produced by KENT. Manufactured from high‑quality GCr15 bearing steel, it delivers low‑noise, stable rotation for general‑purpose motors and mechanical equipmentSKF 集.... The RS rubber contact seal effectively retains internal grease and blocks dust, splashing moisture and fine contaminants, greatly reducing maintenance frequency. It can bear radial loads as well as moderate bidirectional axial loads. Compact dimension makes it a cost‑effective drop‑in replacement for standard 6003 series open‑type or ZZ‑shielded bearings, especially working in dusty or humid operating environments.

Key Features

• GCr15 bearing steel rings & balls, good hardness and wear resistance, long service life
• RS single‑side rubber contact seal: good dust‑proof and splash‑water resistant performance, keep grease inside
• Low friction torque, optimized internal geometry for low‑noise running, suitable for motor‑driven equipment
• Accept both radial load and moderate two‑way axial load
• Simple installation, full interchangeability with ISO standard 6003 series
• Standard steel stamping cage; Cn radial clearance as default; C3 clearance available upon request
• Precision grade: Normal grade P0; P6 precision optional for higher‑requirement motors

Technical Parameters

Typical Applications

Widely adopted for equipment requiring dust & moisture protection, ideal for below scenarios:

1. Small & Medium‑sized Electric Motors: General‑purpose motors, agricultural motors, fan motors, blower motors, generator rotors. Preferred choice for motors working under dusty field conditions.
2. Agricultural & Garden Machinery: Farm implements, garden power tools, irrigation equipment, suitable for heavy‑dust outdoor working conditions.
3. Household Appliances & Power Tools: Washing machines, vacuum cleaners, hand‑held power tools, small fans.
4. General Industrial Machinery: Conveyor rollers, small gearboxes, centrifugal pumps, textile machinery, packaging equipment.
5. Automotive Auxiliary Components: Auxiliary motors, small water pumps and alternators for vehicle ancillary systems.

Note: RS contact seal brings slight friction loss. For ultra‑high‑speed scenarios, open‑type or ZZ metal shield version is recommended.
