10*17*26 Linear bearing KH1026PP

Linear bearing KH1026PPDimension :10*17*26Once ordered, please inform me which type you need?  thanks.

Linear bearing is a kind of linear motion system, used for linear stroke and cylindrical shaft. Because the load-bearing ball is in point contact with the bearing et, the steel ball rolls with the smallest frictional resistance. Therefore, the linear bearing has low friction, is relatively stable, does not change with the bearing speed, and can oain smooth linear motion with high sensitivity and high accuracy. The consumption of linear bearings also has its limitations. The most ant thing is that the impact load capacity of the bearing is poor, and the carrying capacity is also poor. Secondly, the linear bearing has greater ion and noise during high-speed motion. Automatic selection of linear bearings is included. Linear bearings are widely used in sliding parts of precision hine tools, textile hinery, food pahinery, printing hinery and other industrial hinery.

Since the bearing ball is in point contact with the bearing, the load is small. The steel ball rotates with very little frictional resistance, so as to oain high-precision smooth movement.

claification

(1) Standard type, clearance adjustment type linear bearings, open type linear bearings, extended type linear bearings, general-purpose linear bearings

(2) Flanged linear bearings can be divided into: round flange type, method flange type, oval flange type, guided round flange type, guided method blue type, guided oval flange type, and extended round flange type.

According to specifications:

It is divided into two series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, Korea, China, etc. Taking the metric size as the standard, the outer diameter tolerance of the linear shaft is generally h7. LME series are mostly used in Europe, America, Germany, Italy and other regions. With inch size as the standard, there are also metric sizes. The outer diameter tolerance of the linear shaft is generally g6. The structural characteristics of the two series are roughly the same except for the different sizes and aperture tolerances.

According to the shape:

1: Sight cylinder type (shape like a cylinder, generally installed with a circl, used for ocns with small installation size)

2: Flange type (the end or the middle has a mounting flange, which can be installed with screws. The flange is generally divided into three types: round, square and trimmed)

3: Open type (shape like a sight cylinder, with axial slits on the outside, used in ocns where gap adjustment is required, divided into two types: large opening and small opening)

According to performance points:

1: Ordinary type (used for general performance requirements)

2: r type (for life and high load performance requirements)

use

Linear bearings are more and more widely used in precision equment such as electronic equment, food hinery, pahinery, hinery, printing hinery, textile hinery, hinery, instruments, s, tool hinery, hine tools, automobiles and dial three-dimensional coordinate measuring equment Or in the special hinery industry.

Clearance

The inner and outer diameters of adjustable linear bearings and open-ended bearings are measured before the cut, and there will be some elastic deformation ar the cut, and the matching clearance should be measured in the bearing housing (similar to steel retainer bearings and KH bearings). The adjustment direction of the bearing seat with adjustable clearance should be perpendiar to the direction of the bearing cut to ensure uniform clearance. The structural characteristics of linear bearings cannot be rotated, and good guidance is required. Therefore, linear bearings generally use two shafts + four sets Bearings or two shafts + two sets of extended bearings are used in a combination, and the two shafts should be installed sight. Ar the entire aembly is aembled, the nsmiion mechanism must be ibly pushed and pulled by hand without obstruction. The nsmiion power must be sufficient to overcome the bearing friction Resistance, linear bearing friction resistance is approximately one thousandth of the working load.

Maintenance

Linear Bearings

Maintenance of metal linear bearings: lubrication and friction: anti-corrosion oil is injected into the linear bearing. If grease is used for lubrication, first use or organic soent to remove the anti-corrosion oil, and then add grease ar air drying. (It is recommended to use lithium grease with viscosity No. 0.2.) If lubricating with oil, it is not neceary to remove the anti-corrosion oil. According to the temperature change, the lubricating oil of ISO viscosity grade VG15-100 can be used. Shaft lubrication can be from the oil supply Oil, or oil from the oil hole on the outer bearing housing. Since the sealing ring will se off the lubricating oil, oil lubrication is not suitable for non-porous bearings with sealing rings.

Maintenance of plastic linear bearings: Since the sliding film inside the plastic linear bearings is made of s-lubricating plastic, there is no need for additional oil supply and maintenance during use; and because the plastic linear bearings have grooves, even the bearing Or the shaft is packed with dust and there is no need to maintain it. The dust will automatically be taken out of the groove during the movement; only when the sliding film wears out, it can be directly repd by the internal sliding film; maintenance is very convenient.
