Brand Name

NACHI

Type

Ball Screw Support

Description

The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The direction of the load through the balls forms the contact angle. This Super Precision Angular Contact Ball Bearing is tailored toward the machine tool industry. It is Manufactured to very high quality standards (ISO: Class 4, ABEC7) and has a 60 deg contact angle which is great for very high axial thrust loads and ball screw applications. These bearings are generally used in pairs because axial forces are generated when radial loads are applied. These are Universally Ground bearings that can be arranged in any configuration. These bearings are most commonly used in high accuracy and high-speed precision machining center, measuring, robotic and feed actuator applications.
NACHI Super Precision Angular Contact Ball Bearing, Ball Screw Support, Series: TAB, 20 mm Bore, 47 mm OD, 1 Row, 15 mm Width, 60 deg Contact Angle, Open Closure, 41958 N Dynamic/64000 N Static Load, Steel Bearing, Polyamide Cage, 6300 rpm Grease/8000 rpm Oil Maximum, 250 deg F

Application

For high-speed precision machine tools and precision measuring instruments and precision feed actuators such as robots

Features

  • High stiffness
  • Low noise
  • Medium preload is standard
  • High quality bearing steel
  • Ball guided polyamide cage
  • Super honed raceways for high accuracy, improved lubrication and extended life
  • Normally stocked as universal singles
  • Resin cage and more balls than previous ball bearings for greater rigidity
  • Combination bearings are provided with preset preloads, eliminating the need for troublesome installation adjustment using shims and torque measurements
  • A contact angle of 60 deg and has the ability to handle radial and axial loads creates a compact bearing
  • Maintenance free because high performance grease is pre-filled
  • Preset preload for easy installation onto the machine
