This flat roller bearing,comprised of a flat cage and needle rollers, reciprocates on a flat raceway by motion of linear movable components.

• Two material types are available for the cage—synthetic resin and pressed sheet steel.
• FF type molded resin cage -- Multiple cages may be joined together in a serial configuration.
• Press-formed steel plate cage -- Cage to cage jointing is unavailable, but it can be supplied at any specified length.
• double-row synthetic resin cage has an elastic seam along its center line. When immersed in a hot oil bath heated to 70 to 90°C the cage can be “folded” to any desired cross-sectional angle so that it can be fitted to a V-sectioned face.
