Skf 61810 Thin Section Ball Bearing 50mm Bore Open

Product Description

The SKF 61810 is a thin section, single-row radial ball bearing designed for applications where space and weight are critical constraints. It features a 50 mm bore diameter, a 65 mm outside diameter, and a 7 mm overall width, making it well-suited for compact rotating assemblies. The open design requires external lubrication management and allows for easy inspection. With a dynamic load capacity of 1,400 pounds and a static load capacity of 1,070 pounds, this bearing handles moderate radial loads at speeds up to 13,000 RPM. The steel cage provides structural stability across the full speed range. Licensed technicians and millwrights working with precision machinery will find this bearing appropriate for tight envelope designs.

The SKF 61810 is used in industrial and commercial applications where bearing cross-sections must remain narrow relative to bore size. Typical installations include electric motors, pumps, compressors, conveyor systems, light machine tool spindles, and HVAC fan assemblies. Its thin section profile fits into housings where standard deep-groove bearings would not clear. The open configuration suits environments where grease repacking or oil bath lubrication is part of the maintenance routine. This bearing conforms to ISO 15 dimensional standards, which simplifies cross-referencing and replacement sourcing.

Key Features

• 50 mm bore diameter with round bore geometry for standard shaft fitment
• Thin section profile at 7 mm wide reduces axial space requirements
• Dynamic load capacity of 1,400 pounds supports moderate radial loads
• Maximum operating speed of 13,000 RPM suits high-speed light-load applications
• Steel cage construction maintains ball spacing under load and speed
• Open design with no flange and no snap ring for straightforward housing installation
• Conforms to ISO 15 standards for dimensional interchangeability

Compatibility

Designed as an OEM-style replacement or direct-fit bearing for equipment requiring a 50 mm bore, 65 mm outside diameter, 7 mm wide, open thin section ball bearing conforming to ISO 15 standards.

Installation Notes

Installation should be performed by a qualified mechanic or millwright. Always de-energize and lock out the equipment before replacing any bearing. Use a proper bearing press or installation tool to apply force only to the press-fit ring - never strike the bearing directly with a hammer, as this can damage the races and balls. Because this is an open bearing, ensure the housing is clean and apply appropriate lubrication before or immediately after installation per the equipment manufacturer's specification.
