Bearing Sensors

Avoid costly plant shut downs with our express bearing sensor manufacturing service. We stock an inventory of components to manufacture bearing sensors for high and moderate temperature services. Top hat, small profile bearing cap, and double oil seal configurations are routinely assembled with Nickel 120 ohm, Pt 100 ohm and thermocouples.

With over 45 years experience and a manufacturing facility on the West Coast, the days of waiting a week or two for delivery of critically needed embedded bearing sensors is Over! We currently stock many common bearing sensor configurations and have the ability to stock customer specific bearing sensors.

Bearing Sensor Overview

The bearings of industrial rotating equipment operate under arduous conditions - often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the shoe. Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film; thus allowing machine shutdown and maintenance to take place - avoiding the probable catastrophic failure of the bearing and possible damage to its mounting.

Bearing Temperature

The stabilized operating temperature of a bearing is the result of many factors. The key influences on operational temperature are bearing style, lubrication type, operational factors, environmental conditions and level of maintenance The particular bearing style (ball, roller, sleeve, etc.), the shaft mounting style (slip fit, adapter mounted, press fit, etc.) and auxiliary items (housings, seals, shields, flingers, etc.) all contribute to a final operating temperature. For a given set of application conditions, a particular bearing type will generate friction given off as heat. A typical bearing temperature rise range would be 40° to 80°F (4° to 27°C) for most industrial applications. However, a bearing temperature rise over ambient of up to a 120°F (49°C) can be observed at extreme conditions.

Oil Resistant Wire

This is a sensor wire with a fill between the wire, stainles steel braid, and outer jacket. This fill can extend along the entire length of the cable, or a specified portion. The outside of the cable can be sealed with a fitting as well.
