Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
Thomson Ball Bushing® and RoundWay® bearings are shipped with rust preventative oil (unless otherwise specified). Rust preventative oil is not adequate lubrication for use. Prior to installation, bearings require a small amount of grease or oil to operate properly. Which lubrication to choose is dependent on many factors.
A few general guidelines to help select from the available lubrication options:
Below 15% of rated load and high speeds: light weight oil or low viscosity grease
15 to 25% of rated load and medium speeds: Medium weight oil
Between 25 and 50% of rated load: NLGI 1 or 2 grease
Over 50% of rated load: a grease with an EP2 additive. The EP is Extreme Pressure and uses special additives to prevent the grease from breaking down under high pressures. This type of grease will give the steel shafts a dull appearance
Do not use any type of dry lubricant (PTFE powder, graphite powder, etc.) with any recirculating ball or roller type of bearing. While these lubricants are good for sliding motion, they do very little to aid rolling friction.
