Wide Series for The Best Selection and High Perfomance for The Best Design

For a long period  of time, the demand for oilless bearing has been rapidly increasing to meet the industrial requirements for energy and labor cost reductions.

Quickly responding to this trend, YAMADA started its innovative development on oilless bearings which resulted in an assortment of economical self-lubricating bearings. Oil containing, cast iron bearings (YAMADA300) became available for the first time in the world, replacing conventional solid bronze bearings which require frequent oil lubrication. Through continued research and development, this early innovation was followed by the YAMADA500 series which are a combination of a base metal and solid lubricants. YAMADA 500 are low widely used in various industrial fields as self-lubricating bearings.

​

Along with the technological innovations progressing in every industrial field, applications of oilless bearings have been widely spread in a variety of machinery. As a result, YAMADA bearings are now in service in virtually every corner of the world.

Under such circumstances, a carefully designed series of ready-made YAMADA bearings for immediate delivery became more popular and cost effective than order-made bearings which require a design consultation every time. Having recognized such needs early, YAMADA has established a series of standard bearings for various materials and sizes so that the demands from industries for various purposes and applications are dynamically satisfied.

With these standardized YAMADA bearings in stock, adequate YAMADA bearings can be quickly selected to meet industrial design requirements.

YAMADA Bearings Offer Tremendous Advantages

Elimination of oiling devices, machining of oil holes and oil grooves                                    Cost required for oiling devices, including installation and labor costs for machining oil holes and oil grooves or for associated piping installation, can be eliminated, enabling considerable cost reductions.

Reduction in running costs                                A tremendous amount of lubricant oil is usually consumed in a machine shop. Thus, a great cost saving will be achieved by switching into an oilless mode. For example, an 80,000 KW water turbin which consumed an annual of 100L of grease was altered into an oilless operation by employing YAMADA bearings. Using YAMADA bearings lowers running costs through the elimination of both lubricant oil and attendant maintenance operations.

Reduction in maintenance costs                       At a textile fabrics shop, oiling controls are conducted in accordance with an established checklist requiring standard oiling and maintenance for every day, every week, every month and after each specific operation. The maintenance-free mode attained by employing YAMADA bearings will not only solve the problems of oiling operations and oiling devices, but it also extends the service lives of the bearings.

Cost savings from lubricants oil recovery and improved environment                                  Spilled oil causes contamination in working areas when released as sewage, it further contaminates the water in rivers and lakes. The costs for used oil recovery and attendant labor are far from negligible. YAMADA bearings will bring out remarkable cost savings in addition to improved environmental conditions.

Cost savings in desgin                                       If oiling systems are not required (oil holes, lub lines and installation fixtures), design will be simplified. Adoption of standard YAMADA bearings will facilitate further reduction in design costs and time.

More compact design and longer life           YAMADA bearings conserve space because the oiling system is unnecessary and the overall size of the bearing itself is smaller, further enabling a smaller housing and shaft. The compact size will require less material cost as a whole. As being conveniently small in size, YAMADA bearing also has a high load carrying capacity, an accuracy much longer. The easy and quick installation feature are also appreciated.
