JDB-200 steel based precision machined bearing (spiral groove) is a reinforced product with high compressive performance. It can be supplied with oil through the oil groove during operation, creating a layer of diaphragm between the shaft and sleeve, which has the advantage of being more anti biting than single oil lubrication. It is particularly suitable for the support parts of lifting machinery.
