Fingerboard wheel bearing 1x4x1.6mm 691 type open sealed miniature deep groove ball bearing
Description: of Deep Groove Ball Bearing 691
Sometimes referred to as instrumentation bearings or miniature bearings, our miniature bearings are used in applications as diverse as gyroscopes, anemometers, flow meters, miniature gearboxes, small motors and radio-controlled models.
Miniature bearings have flanged outer rings and most of our chrome steel miniature bearings are available as open or with metal shields. Larger sizes may have rubber or PTFE contacting seals or low friction non-contacting rubber seals. While open bearings are lubricated with light oil, shielded or bearings are usually lubricated with grease. Thanks to our in-house relubrication facility, these miniature bearings can be supplied with customer specified oil, grease or dry.
