specification model: 6203-2rs
size: inner diameter 17×outer diameter 40×12 width/mm
external design: double seal (internal steel plate covered with rubber) filling grease: the standard filling temperature range is -20~120 degrees celsius.
bearing material: chrome steel.
shell material: stamped steel.
type: bearing-ball bearing-deep groove ball bearing-single row-double seal selection guide: 2rs double seal-suitable for harsh external environment and medium temperature (-20~90 degrees Celsius) occasions. It is usually used inside the machine with sufficient oil, and the protective covers on both sides of the bearing can prevent the entry of grease and contaminants. (you can use 2RS bearings to clean the internal grease, which is equivalent to opening the bearings).
deep groove ball bearings have deep and continuous raceway grooves. these raceway grooves and balls form a tight expansion, so the bearing can withstand bidirectional radial load and axial load. deep groove ball bearings can be opened or covered, and a protective cover (with a gasket or protective cover) protects the ball from dust.
