Metric rod end bearings built to DIN ISO 12240-1 ( formerly DIN 648 ) schedule K typically are made with inner races or inner rings made of brass, bronze or copper. For many low demand applications, these bearings have proven to give satisfactory service. However, in applications with high loads and/or high vibration levels, they can quickly develop excess clearance do to the deformation of the softer race material. They are typically manufactured with low carbon steel bodies, with limited high strength options. For applications with high loads or high frequency reversing loads, parts in this type of configuration can give less than desired performance.
Aurora Bearing Company offers 3 different series of parts to address these shortcomings.
The Aurora MM-M and MW-M series parts are made with a low carbon steel raceway. This construction offers ball/race durability greater than brass race parts, with a load capacity comparable to the more common configurations.
For applications with vibratory loads, where the body strength or load capacity is not an issue, but severe demands are placed on the bearing itself, the Aurora KM-M and KW-M series offer a heat treated alloy steel raceway around the alloy steel ball in a low carbon steel body.
Concerning the most demanding applications , those that see high loads and vibratory conditions, the AM-M and AW-M series feature the heat treated raceway bearing construction combined with a heat treated alloy steel body. Combining the standard feature of a one piece steel raceway, the MM/MW-M and AM/AW-M series are also offered with Aurora’s exclusive AT series PTFE liner for the optimum in self lubricating/ long life service.
