Solid linear shafts have no additional machined features. They come in pre-cut inch or metric sizes that are either hardened or non-hardened. Hardened shafts have strengthened outer layers and close tolerances for surface finish, roundness, hardness, and straightness; they are suitable for moderate to heavy loads that use ball bearings. Non-hardened shafts have less precise tolerances and are ideal for lighter load applications that use plain linear bearings; they are more accessible to machining.

Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. Owing to their large number of rollers, the bearings have a high load carrying capacity and stiffness.

Drawn Cup Needle Roller Bearings. This bearing type is composed of an outer ring drawn from a thin steel plate by precision drawing, needle rollers and a cage assembled in the outer ring after the raceway surface thereof was hardened (A bearing marked with a suffix including M is subjected to heat-treatment after assembly). Of the bearings with outer ring, this bearing type is a bearing with the smallest section height which enables space-saving and cost-saving. Usually design is so made as to use a shaft as the direct raceway surface without using inner ring. The outer ring of this bearing type is of such a construction that the needle rollers and the cage are not separated from one another, so that the bearing is only press-fitted in a rigid housing with proper fit torque. Thus, this bearing type needs no snap ring, etc. to fix itself in axial direction and, in addition, is easy to handle.

The linear slide rail shaft is made of high quality carbon steel, and the bearing block is made of aluminum alloy, sturdy and durable. Perfect for your DIY CNC routers, no more unwanted errors in your machining work mills, lathes.

ㆍ Shaft dimensions are as follows ㆍMaterial : SUJ2(High carbon chromium bearing steel)ㆍHardness : HRC58~64ㆍSurface finishing : 0.8S~1.6SㆍHardened depth : 0.8~2.5mmㆍStraightness :0.05mm/300mm

Needle roller bearings are rolling bearings with a low radial section height and high load carrying capacity, which are used as non-locating bearings and are part of the group of radial needle roller bearings. These bearings comprise machined outer rings, needle roller and cage assemblies and removable inner rings, i.e. they can be supplied with or without an inner ring in accordance with the application. In contrast to the outer cups of drawn cup needle roller bearings, which are produced by forming methods, the bearing rings are machined. Due to their non-locating bearing function, the bearings cannot guide the shaft axially in any direction.

A case unit that incorporates a standard linear bushing into a small and lightweight aluminum case. Linear bushing LM type is a linear motion system that is used in combination with a cylindrical LM shaft and moves infinitely linearly. Since the load ball and the LM shaft are in point contact, the allowable load is small, but linear motion is performed with the minimum frictional resistance, and high-precision and light motion can be obtained. The outer cylinder uses high-carbon chromium bearing steel, and after heat treatment, the content and outer diameter are ground. The dimensional tolerances of each part of the linear bush are standardized and compatible. The LM shaft can be processed by cylindrical grinding, which is easy to process, so a high-precision fitting clearance can be obtained. The retainer that guides the row of balls is formed in one piece, so it can be guided accurately in the direction of travel of the ball and stable running accuracy can be obtained. Because it uses a retainer that is integrally molded with synthetic resin, the sound during exercise is low and the lubricity is excellent. It can be easily installed simply by fastening the bolts to the table. Special synthetic rubber seals are incorporated on both sides to prevent foreign material from entering and prevent leakage of grease. Precision equipment such as office automation equipment and peripheral equipment, various measuring instruments, automatic recorders, digital three-dimensional measuring machines, punching press, tool grinder, automatic gas cutting machine, printing machine, card sorter, food packaging machine Industrial machinery slides, etc.
