1635VV Inch‑Size Deep Groove Ball Bearing 19.05x44.45x12.7 Double‑Sided Non‑Contact VV Rubber Seal

1. Product Overview

1635VV is inch‑size single‑row deep groove ball bearing. Dimensions:19.05 mm bore × 44.45 mm outer diameter ×12.7 mm width (3/4" ×1‑3/4" ×1/2").
Suffix explanation:
‑ VV: Double‑sided non‑contact rubber seal. Low‑friction design, good dust‑proof performance, retain factory pre‑filled grease, maintenance‑free construction, not suitable for heavy liquid splash conditions.

Classic deep‑raceway structure, capable of bearing bidirectional radial load together with moderate bidirectional axial load. Adopt stamped steel cage for even ball separation, realize low‑friction and stable high‑speed rotation. All rings and rolling elements adopt fully quenched GCr15 chrome bearing steel. Widely used for inch‑standard small‑motors, power‑tools, light conveyor rollers, textile equipment, agricultural auxiliary machinery and compact general‑purpose machinery requiring non‑contact sealing and high‑speed performance.

3. Core Advantages

• VV double‑sided non‑contact rubber seal: Lower running torque compared with contact‑type seals, excellent dry‑dust blocking performance, lock internal pre‑filled grease for long‑term maintenance‑free running.
• Inch‑standard dimension, compact structure, fits equipment designed according to imperial shaft‑housing specifications, convenient replacement for original inch‑series bearings.
• Deep‑groove ball bearing structure, bears radial load plus moderate bidirectional axial load, adapts to composite‑load compact transmission shafts.
• Super‑finished raceway and steel‑ball surface, low vibration and low‑noise performance, stable continuous‑running performance for small‑motor and power‑tool‑grade equipment.
• GCr15 overall quenched bearing steel, stable metallographic structure, good anti‑fatigue and wear‑resistant performance for cyclic working‑conditions.
• Stamped‑steel riveted cage, light‑weight and high rigidity, evenly distribute rolling‑element stress and reduce high‑speed noise.
• Fully interchangeable with global standard 1635VV inch‑series bearings, direct replacement without housing modification.
• Rich custom options: P0/P6 precision grade, multi‑clearance‑groups, stainless‑steel variant, OEM outer‑ring laser marking, neutral export anti‑rust carton, special‑temperature grease filling.
