I. From inside the riding surface of the slide, take the razor knife and cut into the leaking joint.
Remove the old sealant that has lost its elasticity.
II. Take a clean rag or cloth with acetone and apply to the joint. This will clear all remaining
dirt, debris, and water from the old sealant.
III. Apply new sealant in the area where sealant has been removed. Using the putty knife, work
the sealant into the joint to ensure that the sealant has fully covered the void.
IV. Remove excess sealant with the putty knife, and wipe the joint clean with a clean cloth and
acetone. Use the acetone sparingly as using too much can deteriorate the remaining
V. Allow up to twenty four hours for the sealant to properly cure. If this is not possible, allow as
much time as possible.
IV. Basic parameters and technical conditions of the Class B vault door
i. Products must comply with the requirements of Class B vault door specified in GA / T143-1996 of the National Public Industry Standards as well as requirements of Class 2 vault door specified in JR / T0001-2000 and Class 1 combination lock specified in JR / T0002-2000 of the National Financial Industry Standards.
ii. The Class B vault door basically consists of the frame, leaf, day gate, digital mechanical cipher lock and special lock.
3．金库门的门框、门扇正面四周周边间隙不大于1mm，不应有可以直接窥视到门内的缝隙，门框、门扇的表面平整，外表面的平面度不大于2 mm，内表面的平面度不大于4 mm。
iii.

The overall wear resistance of the series of EPB
engineering plastic bearings is improved by use of high-performance engineering
plastic as principal raw material into which high-strength fiber and special
solid lubricant are placed by means of modification of polymer materials; the
net structure of the fiber can increase the principal raw material’s strength,
while the composition of the lubricant gives the series of EPB excellent self-lubricating and
Whether for automobile industry in need of high
durability, or for applications under conditions such as high speed,
underwater, high temperature and corrosion, or for food industry required to
meet standards of FDA, CSB always can provide customers with individual
Such bearings are most widely applied as self-lubricating plastic bearings; with the highest universality, the EFB plastic bearing can be used in many occasions when the operating temperature is at 80℃ or below; EPB3 features high universality whether from load or operating temperature; EPB7 and EPB13 are both recommended to be used in occasions in need of good wear resistance but in no need of high cost-performance; among versatile bearings, besides a good wear resistance, EPB19 features the highest resistance to temperature so that it can be used even at high temperature of 150℃ for a long time.
● A maintenance-free self-lubricating plastic linear bearing. Noiseless. Appropriate for continuous use in extremely severe dusty environment. Permitted to be cleaned with the cleaning solution for food & drug packaging machinery.
●Maintenance-free, suitable for long-term dry running, and noiseless;
●Suitable for use in dusty environment for a long time;
● Corrosion-resistant, suitable for being cleaned with disinfectant;
● Because of the design of skewed slot, the series boasts stronger protection for shaft;
● The skewed slot is narrowed for an enhanced carrying capacity;
