Many people think it is easy to buy bearings, but the follow-up maintenance is very troublesome. To solve this trouble, maintenance-free bearings appeared later, and there was no need to maintain the bearings.
Maintenance-free bearing refers to a rolling bearing that can work stably for a long time without maintenance from installation to fail. It is an advanced rolling bearing technology with excellent performance of maintenance-free, high performance, long life, more environmentally friendly, reliable, and durable. It can be seen literally that the so-called maintenance-free means that it does not require maintenance or requires very little maintenance. Maintenance-free is generally for self-lubricating bearings, you do not need to add oil, you do not need to maintain it during the service cycle.
Around the world, people have put forward more and more stringent requirements on energy utilization, efficiency improvement, and environmental protection. Bearing technology tends to be more efficient, energy-saving, and environmentally friendly. , The era of high performance that is resistant to special environments and maintenance-free has arrived.
The universal joint cross still needs regular maintenance, so that it can be used for a longer time.
