Description:Cat heavy duty needle bearings are high accuracy bearings designed for maximum load capacity where the application requires high static, dynamic or shock loads. The solid machined outer ring provides high rigidity and allows the bearing to handle higher loads. A lubrication groove and hole in the OD facilitates re-lubrication through the outer ring.Attributes:• Outside Diameter: 140 mm (5.511 in)• Inside Diameter: 110 mm (4.330 in)• Height: 30 mm (1.181 in)• High load carrying capacity and rigidity• Through hardened needle rollers• Supports high rotational speeds• Requires minimal radial mounting spaceApplication:Typically used where toughness, durability and high performance is critical such as gearbox and transmissions.
