The reliable performance and durable construction of NTN’s Green Lines Series bearing units makes them a smart solution for practically all types of common applications. Green Line bearing units’ unmatched selection of housing styles, insert types as standard makes it NTN’s tried and true Mounted Ball Bearing Unit Series.

Green Line units are available in both metric and inch shaft sizes throughout our set screw, eccentric, and adapter sleeve inserts. With bore sizes range from ½” to 4”, the Green Line is a highly versatile and industry interchangeable product line. The cast iron bearing housing is designed to provide maximum strength in even the toughest applications. With this strength, the ability to allow for misalignment of +/- 2° and relubrication capability, you just can’t go wrong.

Green Line units also feature double-sealing construction comprised of an oil-resistant rubber seal and a flinger. The double sealing construction boasts a sealing performance that is much more reliable than standard seals since the ingress path for dust is long, and because excess grease, which purges between the seal and the flinger when the bearing is in operation, serves as a seal.
