Single Row Ball and Roller Bearings
A single bearing failure can shut down an entire production line. The fix starts with sourcing the right component from the right distributor.
Alpine Bearing is a leading single row ball and roller bearing distributor with thousands of SKUs in stock and ready for same-day shipment. Our sales engineers help OEMs and replacement buyers find the exact single row bearing their equipment requires.
How Single Row Bearings Are Used
Single row bearings contain one row of rolling elements, either balls or rollers, positioned between an inner and outer race. This simple yet effective configuration supports radial loads, axial loads, or both depending on the bearing type.
OEMs and maintenance teams across aerospace, medical, and robotics rely on single row bearings for everything from high-speed spindle applications to precision instrument assemblies. Single row deep groove ball bearings excel under combined loads at high speeds.
Single row angular contact ball bearings take on heavier thrust loads with precision, while single row cylindrical roller bearings carry the highest radial loads of the three. Alpine’s sales engineers help you determine which configuration fits your equipment and application.
Types of Single Row Bearings We Carry
Alpine Bearing distributes single row ball and roller bearings across multiple configurations to serve OEMs and the replacement market. Each type handles different load conditions, speeds, and application requirements. Our sales engineers help you identify the right match for your equipment.
Single Row Deep Groove Ball Bearings
Single row deep groove ball bearings use a single row of balls seated in deep raceway grooves on both the inner and outer rings. This geometry allows them to support radial and axial loads simultaneously at high speeds with minimal friction.
Their versatility makes them one of the most widely used bearings in robotics, medical devices, and general industrial equipment.
Single Row Angular Contact Ball Bearings
Single row angular contact ball bearings position the raceways at an angle relative to the bearing axis, enabling them to carry combined radial and axial loads in one direction.
The steeper the contact angle, the greater the axial load capacity. Aerospace and medical OEMs rely on these bearings for precision assemblies that demand tight tolerances and high-speed capability.
Single Row Cylindrical Roller Bearings
Our single row cylindrical roller bearings replace balls with cylindrical rolling elements that distribute loads across a wider contact surface. This gives them the highest radial load capacity among single row bearing types.
They thrive in heavy-duty applications where machine tool spindle performance and durability under sustained radial stress are critical. Alpine’s failure analysis services help optimize roller bearing selection and lifespan.
How to Choose the Right Single Row Bearing for Your Equipment
Selecting the right single row bearing starts with understanding your application’s specific demands. Alpine’s application engineering team evaluates these key factors to match you with the optimal component:
- Load type and direction determine whether you need a deep groove, angular contact, or cylindrical roller configuration. Radial-dominant applications favor single row cylindrical roller bearings, while combined loads often call for single row deep groove ball bearings.
- Speed requirements narrow your options further. Single row angular contact ball bearings and deep groove ball bearings handle high RPMs, while cylindrical roller bearings prioritize load capacity over speed.
- Operating environment affects material and lubrication choices. Corrosive, high-temperature, or cleanroom conditions require specific configurations. Alpine’s re-lubrication services with 100+ lubricant types ensure your bearing performs in its intended environment.
- Space constraints matter in compact assemblies. Single row bearings offer a slimmer cross-section than double row alternatives, making them ideal for tight-fit medical and robotics applications.
- Replacement compatibility is critical for the aftermarket. Alpine stocks 20,000+ SKUs and ships same-day so your equipment gets back online fast.

Frequently Asked Questions About Single Row Bearings
Learn more about our single row bearings through these commonly asked questions.What is the difference between a single row and double row bearing?
A single row bearing contains one row of rolling elements between the inner and outer races, while a double row bearing contains two. Single row bearings fit narrower assemblies and perform well at higher speeds. Double row bearings handle heavier loads and provide greater stability but require more axial space.
Can a single row bearing support both radial and axial loads?
Yes. Single row deep groove ball bearings and single row angular contact ball bearings both handle combined radial and axial loads. The load capacity in each direction depends on the bearing type and contact angle.
How do I find the right single row bearing size for my equipment?
Alpine Bearing offers a bearing size finder tool that lets you search by dimensions and specifications. If you need additional support, our sales engineers can cross-reference part numbers and recommend the correct replacement.
Does Alpine Bearing offer same-day shipping on single row bearings?
Yes. Alpine stocks over 20,000 SKUs across all single row ball and roller bearing types and ships in-stock orders the same day. We also offer inventory management services, including JIT, Kanban, and kitting for customers with recurring bearing needs.
