*For continuous operating temperature of 176 deg. F.
The housings are completely sealed and allow for mounting in any position. All reducers are run-tested and supplied filled with oil (except reducers with 8 mm shafts which use grease). For oil-level inspection, a removable sight gauge is provided which can be relocated as needed, depending on the mounting orientation. For the light-duty version, the plug screw serves as an oil level and filler plug.
Under normal operating conditions, the gear reducers are maintenance free. In the case of continuous running in the upper power range, the recommended oil change interval is every 2,000 hours of operation. In the case of low peripheral speeds, the gear reducers can be filled with grease up to the sight gauge location.
