Its construction is simple and cost-effective. The N/O linear guideway assumes the task of being the lateral linear guideway for the table. As the surface guideway is adjusted level with the N/O, the linear guideway systems can be interchanged – depending on whether the grinding  spindle is mounted to the right or left....

The majority of angular contact bearings use phenolic type cages and these are exceptional good for a wide range of conditions and particularly for high-speed since they are outer ring located. However, there are advantages to using TYN cages in certain applications, particularly in grease lubrication. TYN is a polyamide material and this cage is designed to be ball guided. Reduced Cage Noise In certain applications cage noise can occur in grease...

No one knows who invented the planetary gearbox, but it has been in use since the 15th century.Planetary Gearboxes is an old mechanics fundamental that is still being used for new eading innovative technology like 3D printing, and new methods of transport. Planetary gearbox consist of an internal toothed ring gear to which are set 3 planets mounted on the planet carrier engaging also with the sun gear and reduced output speed is taken through pla...

Design Variants To allow the bearings to accept the maximum number of balls, four point contact ball bearings are designed with split inner ring or with split outer ring so these bearings have two basic types, one is featured two half inner ring(QJ series), the other is featured two half outer ring(QJF series). TBB four point contact ball bearings have the contact angle of 35°. We can both provide QJ series and QJF series on request. TBB four po...

Size from 2mm to 6m Bearings vary in sizes. The smallest “miniature bearing” in the world is with ID 0.6mm× OD 2.0mm× Thickness 0.8mm, which is used in micro motor. The large-size bearing, with an outer diameter of 6m and a weight of more than 15 tons, is used in the large shield machine for tunneling. This kind of large bearing is used when excavating the cross sea tunnel under the Dover strait connecting Britain and France.  ...

With the wide application of PWM and IGBT in motor, the problems caused by electromagnetic damage such as electric corrosion of bearing are more and more prominent. What causes electromagnetic damage of bearing? Common mode voltage is the main cause electromagnetic damage. When the bearing is running at high speed, there will be a fluid oil with strong insulation between the roller and the inner & outer raceways. Due to the constant change of...

When and How to Consider a Custom Linear Bearing
Bearing knowledge / 2019-07-15

Custom linear bearings can help solve unique problems. Understanding what situations demand a custom linear bearing is key. Each application is a little bit different. For every load that can be perfectly supported by a stock bearing, there are others that require a customized solution. A project may involve specialized environments, extreme performance demands, tight scheduling, and more. Let’s focus on some of the techniques enginee...

Reliability by Design – Selection of theLubrication
Bearing knowledge / 2019-07-12

“Bearings are as good as their lubrication”. The lubrication is the most important factor for bearing life. Several actual statistics show that incorrect lubrication causes more than 50% of premature bearing failures.A correct lubrication must cover: 1. The correct lubricant. Oil or grease? Viscosity? Temperature range? Anticorrosive properties? EP properties? Consistency of the grease? Etc. 2. The correct lubrication system...
