61818 2RS ZEN 90x115x13 mm Deep Groove Ball Bearing

Applications

The 61818 2RS ZEN bearing is a premium-grade deep groove ball bearing designed for demanding industrial environments. With inner diameter 90 mm, outer diameter 115 mm and width 13 mm, it fits seamlessly into bearing housings and bearing units within heavy-duty gearboxes, large motors, conveyor drives and other mechanical assemblies. Thanks to its sealed design and robust construction, this unit offers superior performance in manufacturing plants, power generation, material handling and maintenance operations.

Advantages

• Sealed on both sides (2RS): Rubber contact seals ensure lubricant retention and prevent ingress of dust and moisture—resulting in higher reliability, extended service life and reduced downtime.

• High-durability deep groove construction: The single-row ball bearing design with deep raceways manages both radial and moderate axial loads, offering stable operation under dynamic conditions and enhancing the lifespan of the bearing unit.

• Standardised dimensions (90 x 115 x 13 mm): Facilitates quick replacement, simplifies inventory management and reduces procurement complexity, enabling streamlined maintenance in industrial settings.

• Enhanced application scope: Ideal for industrial applications where units must deliver high performance with minimal maintenance—such as bearing housings, drive modules, heavy machinery, obudowa łożyskowa (bearing housing) or obudowa jednostki łożyskowej.

• Strong B2B focus: Designed for engineers, procurement specialists and maintenance professionals who require a reliable component with proven quality, dimension consistency and sealing integrity.

FAQ

Q1: What does the “2RS” suffix denote in this bearing model?
A1: The “2RS” designation indicates that the bearing is sealed with rubber contact seals on both sides. This enhances protection from contaminants and retains lubricant, thereby increasing service life.

Q2: In what types of industrial applications can the 90x115x13 mm size be used?
A2: This size is consistent with large motors, heavy-duty gearboxes, bearing housings, roller drives and industrial machines where radial loads dominate and sealing reliability is critical.

Q3: How does a deep groove ball bearing differ from other bearing types in terms of load management?
A3: Deep groove bearings support radial loads and moderate axial loads due to their groove geometry. They offer lower friction, smooth operation and ideal durability for general industrial applications requiring a unit bearing or bearing housing.

Q4: What maintenance benefits does the 2RS sealed bearing provide?
A4: With sealed construction, lubricant retention is improved and external contamination reduced. This leads to fewer re-lubrication intervals, less frequent bearing changes and lower overall maintenance cost.
