Reasons to Choose Us ?

Reasons to choose Guomai Bearings as your independent needle roller/rolling bearings partner

1. Bearing designing: Guomai has our own bearing R&D team and adopts Germany technology. This enables us to provide OEM and ODM service to you.
2. Production process: We strictly follow the 5S production process and acquired ISO9001:2008 quality management system certificate. Besides, we introduced from abroad world famous brands lathes and heat treatment equipment, this enables us to provide high precision bearings with similar quality to world famous brands such as SKF, ,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Materials: To ensure the high quality of bearings, we use high carbon chrome bearing steel which provides high rigidity, and high resistance to abrasive wear to produce the bearings. Low carbon cold rolled steel and low carbon stainless steel is also used according to customers' requirements.
4. Quality inspection: All bearings will be strictly tested before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to guarantee all bearings are qualified with the standards.
5. Lubricants: Suitable lubricants are used to protect the bearings from oxidation or corrosion of parts thus enable our bearings with longer lifetime, low noise and better high temperature performance. Selection of lubricants is generally governed by the bearing application. Right choice of high quality lubricants could prevent metal to metal contact and conduct heat away from the bearings.
6. Packing: Guomai bearings pay attention to every detail in the bearing production process. We adopt plastic bag, Kraft paper, thick paper box and cartons to protect the bearings from unexpectable damage during the transportation and warehouse stock.
7. Factory direct marketing: We are the factory and not the distributor or trading agent, so we could provide the same quality with competitive price.

Bearing Description

What is Cam Follower Needle Roller Bearing?

1.KR design cam followers are fitted with a needle roller and cage assembly. They are also available with a full complement needle roller set, which is identified by the letter V at the end of the basic designation. The outer ring is axially guided by the pressed-on flange ring and the head of the stud, which also serves as an integral flange.

2. KR design cam followers without a designation suffix or with the designation suffix B have a narrow gap between the outer ring and the two flanges that serves as a gap-type seal.

 3. KR design cam followers are also available with an axial sliding ring made of PA66 on both sides, identified by the designation suffix PPA , PPSKA  or PPXA. In the radial direction, the sliding ring forms a narrow labyrinth seal with the outer ring to protect against coarse contaminants. In the axial direction, the sliding ring serves as a contact seal to reliably retain grease in the bearing. This improves the lubrication conditions in the bearing, keeps friction and frictional heat low, and extends grease life.

Bearing feature:
Instead of an inner ring, cam followers have a solid stud (pin) that is threaded so that the cam follower can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.
All three cam follower designs have the same main dimensions. The differences are in their internal design, which make them suitable for various operating conditions. In contrast to ball and roller bearings, where the bearing size refers to the bore diameter d, for cam followers the size refers to their outside diameter D.
All designs are available with a concentric seat (fig. 1) or an eccentric collar (fig. 2) on the stud. An eccentric collar, which has a shrink-fit onto the stud, enables less stringent positioning tolerances to be specified for associated components. The values for the adjustable eccentricity are listed in the product tables. An eccentric collar is identified by the letter E at the end of the basic designation.
