SS6205-2RS Stainless Steel Deep Groove Ball Bearing 25x52x15mm Double Rubber Contact Seal Anti-Corrosion

1. Product Overview

SS6205-2RS is single row stainless steel deep groove ball bearing, standard ISO metric dimension 25mm inner bore × 52mm outer diameter × 15mm width.

Prefix & Suffix Code Explanation:

• SS: Full stainless steel construction, inner ring, outer ring and steel balls adopt high hardness AISI440C stainless steel, cage AISI304 stainless steel sheet, outstanding anti-rust, moisture and weak acid corrosion performance
• 6205: Light series deep groove ball bearing, nominal bore size 25mm
• 2RS: Double-sided integrated rubber contact sealing structure, retain internal grease, block water splash, dust and organic residues, maintenance-free for long-term operation

Classic deep raceway structure can bear radial load and moderate bidirectional axial load simultaneously, low friction, low noise and stable high-speed rotation performance. Pre-filled food-grade anti-wear grease before delivery. Widely used in food processing equipment, marine small transmission parts, agricultural irrigation machinery, beverage filling equipment, laboratory instruments, textile humid workshop equipment and all working conditions with water, moisture and corrosive medium.

3. Core Advantages

1. AISI440C stainless steel rolling components, excellent rust resistance, no oxidation under long-term water splash, high humidity and weak acid mist environment, perfectly fit food, marine and aquaculture anti-corrosion scenarios.
2. Double-sided 2RS full contact rubber sealing, dual barrier protection, effectively isolate clean water, food residues, workshop dust and light chemical mist, lock internal grease to avoid loss.
3. Standard deep groove ball bearing structure, balanced bearing capacity of radial load and moderate two-way axial thrust load, widely matched with various light and medium load rotating equipment.
4. Ultra-precision superfinishing grinding stainless steel inner and outer raceways and steel ball surfaces, smooth rolling contact surface, low vibration and quiet operation during continuous high-speed rotation.
5. Stabilized quenched stainless steel with uniform metallographic structure, good wear resistance, extend service life under cyclic humid vibration environment.
6. Lightweight stamped stainless steel riveted cage, evenly separate steel balls to reduce collision noise, compact overall size to save equipment installation space.
7. Standard ISO metric interchangeable dimension, fully compatible with global SS6205-2RS stainless steel bearings, direct replacement without modifying shaft and housing structure.
8. Rich customizable options: P0/P6/P5 precision grade, C3/C4 enlarged clearance group, open type / ZZ metal shield variant, food-safe white grease pre-filling, OEM laser marking, neutral export anti-rust carton packaging.
