Thomson® SUPER20-NB THOSUPER20-NB

The Super Ball Bushing® bearing has been the industry standard for self-aligning linear bearings for over twenty years. This bearing provides three times the load capacity or 27 times the travel life of conventional linear bearings. Besides the dramatic increase in load capacity, the Super Ball Bushing® bearing is self-aligning, lightweight and adjustable with a low coefficient of friction. It is a quick and easy replacement for high friction plain bearings. The wear-resistant, engineered-polymer retainers and outer sleeves reduce inertia and noise in critical, high speed applications.

Thomson® Super Ball Bushing® Linear Bearing, Adjustable Closed, 1-1/4 in Shaft Dia, 2 in Outside Dia, 2-5/8 in Length, 1500 lb Dynamic, Steel Bearing, 3 m/s Maximum, 185 deg F

• A coefficient of friction as low as 0.001 and allows the use of smaller, less expensive motors, belts, gears and ball screws when replacing high-friction, plain bearings
• A self-aligning capability up to 0.5 deg compensates for inaccuracies in base flatness or carriage machining
• Accelerations as high as 150 m/sq-s and steady state travel speeds up to 3 m/s without the derating factors commonly required with linear guides
• Double-lip integral wipers that keep out dirt while retaining lubrication and travel life is maximized
• Lightweight, wear-resistant, engineered polymer retainers and outer sleeves that reduce inertia and noise
• The Super Ball Bushing® bearing is self-aligning, lightweight and adjustable with a low coefficient of friction
• The wear-resistant, engineered-polymer retainers and outer sleeves reduce inertia and noise in critical, high speed applications
• Radially floating bearing plates when installed in an adjustable housing, the Super Ball Bushing® bearing may be adjusted to a specific diametrical fit-up for accurate and repeatable movement
• Nylon ball
• Self-aligning
