6015-2RS Deep Groove Ball Bearing for Industrial Motors & Machinery | 75×115×20 mm

6015-2RS Deep Groove Ball Bearing for Industrial Motors & Machinery | 75×115×20 mm

The 6015-2RS is a robust, Light Series deep groove ball bearing engineered for environments that demand high load capacities and strict contamination control. Featuring double rubber contact seals (2RS), this bearing effectively blocks moisture, dust, and heavy particulates from entering the raceway. With a 75 mm bore, 115 mm outer diameter, and a 20 mm width, this model is a standard requirement for heavy-duty electric motors, pump shafts, and industrial drives. Manufactured with the technical rigor developed over Welink Bearing’s 15 years of industry experience, the 6015-2RS ensures long-term operational stability and reduced maintenance downtime for engineers and technicians.

6015-2RS Deep Groove Ball Bearing 75x115x20 mm | ISO 60 Series – Light | Double Contact Seals

Designed for standard industrial and commercial applications, this bearing features optimized deep groove geometry to support substantial radial loads alongside moderate axial loads. The NBR rubber contact seals securely retain factory-filled, high-quality grease, keeping the bearing sufficiently lubricated for reliable, continuous operation at speeds up to 3,400 r/min.

  • Escalator and Elevator Drive Systems

Key Performance Features

01. Standardized Light Profile with High Load Output

Built to ISO 60 series standard dimensions, the 75x115x20 mm configuration balances a relatively compact cross-section with high structural rigidity. It is tailored for mechanical setups where maximum dynamic load capacity (41.6 kN) is required without sizing up to a heavier series.

02. 2RS Double Contact Sealing

Unlike non-contact metal shields (ZZ), the 2RS variant utilizes double NBR (Nitrile Butadiene Rubber) contact seals. The seal lip physically contacts the inner ring, providing superior defense against water ingress, slurry, and fine dust, making it highly effective for outdoor or harsh factory operating conditions.

03. Machined for Low Vibration Under Load

Precision-ground raceways and high-grade steel balls ensure tight dimensional tolerances. This results in stable internal clearance, preventing excessive heat generation and minimizing mechanical noise in sensitive commercial equipment or high-speed motor applications.

Design & Configuration

The 6015-2RS is pre-lubricated with high-grade grease and sealed for life, eliminating the need for regular relubrication. It is built to handle heavily contaminated or damp environments where open or shielded bearings would fail prematurely due to debris. For mechanical environments with exceptionally high speeds where water exposure is not a risk, a shielded (6015-ZZ) or open (6015) configuration is recommended to reduce seal friction.

"A heavy-duty component for industrial power transmission, the 6015-2RS provides engineers with the reliable moisture resistance and high radial load capacity necessary to keep critical machinery running smoothly."
