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.
