Bearing

Pressurized air applied to the air bearing’s cylinder creates a stiff cushion of air to support the piston. The airflow effect prevents the piston from contacting the cylinder wall, resulting in virtually unlimited piston life, no lubrication, and clean operation.

When design decisions hang in the balance, which is more important: precision or expediency? Comments to “Rugged bearings hold the weight of heavy equipment"

Who would have thought something as ordinary as a bearing could spark a person’s imagination? DualVee bearings from Bishop-Wisecarver Corp., Pittsburg, Calif., did exactly that for Jamie Hyneman when he was building a fighting robot.

The 5997 MatTop chain from Rexnord Industries LLC tried Rexnord Duralon bearings in the cooler and in hot water spray. Inspections after an eight-month trial revealed no visible wear, so the company planned to replace the remaining bearings.

Linear precision bearings, in both inch and metric sizes, have three times the load capacity and can provide up to 27 times the normal travel life of conventional slide bushings.

Could self-lubricating bearings with a wide temperature range actually save you money?

The 384-page B620 Bearing catalog/ handbook features over 4,978 off-theshelf bearings.

Explorer deep-groove ball bearings are designed with precise tolerances and surface finishes for low-friction operation.

Polyurethane-coated bearings reduce wear on cam tracks, provide better traction, and cut process noise.

Bearings for big loads demand that designers pay special attention to contact area, heat management, and resiliency.

New forkstyle release bearings are used in drag-racing clutches.

PRT slewing rings replace ball bearings with two sliding elements made of self-lubricating iglide J polymer.

Preset clearance, positive locking, and torque confirmation ended installation problems.

Hydrodynamic pressure bearings in the BBSPLN Series are 30% lighter and cost less than conventional ball bearings.

Composite metal-polymer bearing retainers made from silver-coated polyamide-imide feature precision machining to keep tolerances on cage diameter, ball-pocket location, and piloting-land interface under 0.002 in.
