Sprag Clutch Bearings – Reliable One-Way Bearings from Bearing King
At Bearing King, we take pride in offering a diverse and comprehensive range of sprag clutch bearings to meet the demands of various industrial applications. Whether you're seeking high-performance one-way bearings for use in automotive systems, conveyor systems, or heavy machinery, our extensive collection delivers the quality and durability you can trust.
Sprag clutch bearings—also known as one-way bearings or overrunning clutches—are precision components that allow rotation in one direction while preventing it in the opposite. Unlike roller clutches or other forms of backstopping devices, sprag clutches use specially shaped, asymmetrical elements known as sprags, which wedge between the inner and outer races when rotation occurs in the undesired direction. This simple yet highly effective design enables them to perform reliably even under high torque and speed conditions.
At Bearing King, we stock a broad selection of sprag bearings clutch products from leading brands and manufacturers. These bearings are ideal for applications requiring indexing, backstopping, or overrunning functionality, and are commonly used in gearboxes, starters, transmissions, and industrial machinery across multiple sectors.
