IKO BA 1910 Z,BAM 1910 Nots
Note(1) Allowable rotational speed applies to oil lubrication. For grease lubrication, a maximum of 60% of this value is allowable.
Remarks1. ”W” in the identification number indicates that rolling elements are arranged in double rows.
2. Shell Type Grease Retained Full Complement Needle Roller Bearings are provided with prepacked grease. Standard type and
closed end type bearings are not provided with prepacked grease, so perform proper lubrication when using these types of
bearings.
