SKF
Sealing Solutions for Motorcycles and Bicycles
SKF provides an integrated range of sealing solutions tailored to the unique requirements of motorcycles and bicycles. Beyond the fork seals, this category includes seals for the drivetrain (countershaft, sprocket seals), wheel bearings, suspension linkages, and headset bearings. These seals must be compact, lightweight, and capable of withstanding environmental punishment: road spray, pressure washing, mud, and for bicycles, grit and sweat from intense athletic use. SKF utilises low-friction materials and advanced lip geometries to minimise pedalling resistance for cyclists and maintain supple suspension action for motorcyclists. The seals are also engineered for easy serviceability, often as part of standard maintenance kits. Whether for a grand prix racing motorcycle or a mountain bike descending an alpine trail, SKF’s sealing solutions contribute to safety, reliability, and performance.

Motorcycle Countershaft and Wheel Bearing Seals
The countershaft (output) seal behind the front sprocket must withstand chain lubricant, road grime, and high-speed rotation. SKF’s motorcycle specific seals provide long-life, leak-free performance, protecting the transmission output bearing and keeping the rider’s left boot clean. Wheel bearing seals similarly protect the hub bearings, ensuring reliable wheel rotation and safety.
Bicycle Sealing Innovations from SKF
In high-end mountain bikes, SKF’s low-friction seals on suspension pivots and bottom bracket bearings resist mud and water while adding minimal pedalling resistance. For e-bikes, SKF provides durable seals for motor and gearbox shafts that withstand the higher torques and speeds of electric assist, contributing to the overall system durability and range.
