P0-public service level meets the 0 level of the international standard ISO rules; the code is omitted; does not indicate.
The P6-public service level meets the 6th level of the international standard ISO rules.
P6X-6X grade tapered roller bearings conforming to the international standard ISO rules.
The P5-public service level meets the 5th level of the international standard ISO rules.
P4 - The level of public service is in line with the international standard ISO level 4.
P2-Public service level meets the international standard ISO level 2 (excluding tapered roller bearings).
The SP-scale accuracy is equivalent to 5 steps; the rotation accuracy is equivalent to 4 (double row cylindrical roller bearings).
The UP-scale accuracy is equivalent to 4 levels; the rotation accuracy is higher than 4 (double row cylindrical roller bearings).
HG-scale accuracy is equivalent to 4; rotation accuracy is higher than 4; lower than 2 (spindle bearing).
.7) 1 set of clearance C1- clearance fit rules; less than 2 sets.
C2- clearance fits the two rules of the norm; less than 0.
C0- clearance fits the 0 group of the specification rules; the code is omitted; does not indicate.
C3- clearance fits the three rules of the norm; greater than 0.
4 groups of C4-play fit rules; greater than 3 groups.
5 groups of C5-play clearance rules; greater than 4 groups.
1) The public service level code and the clearance code need to be indicated together; the combination of the public service level code (not indicated by P0 level) plus the upstream gap group number (not indicated by the 0 group) indicates.
Example: P63=P6+C3; indicates the bearing public service class P6; radial clearance 3 groups.
2) Non-normative clearance; in the case of special radial clearance and axial clearance; the relevant limit values ​​shall be indicated by the number of microns after the letter R (radial clearance) or A (axial clearance); The numbers should be separated by small dots.
Example: 6210. R10. 20-6210 bearing; radial clearance 10 microns to 20 microns.
.8) Bearing F3-low noise bearing for testing noise. Mainly refers to cylindrical roller bearing and deep groove ball bearing with inner diameter d greater than 60 mm. Example: 6213. F3.
G-low noise bearing. Mainly refers to deep groove ball bearings with inner diameter d less than or equal to 60 mm. Example: 6207. G.
.9) Heat treatment S0-bearing rings are treated by high temperature tempering; working temperature can reach 150 degrees Celsius.
The S1-bearing ring is treated by high temperature tempering; the working temperature can reach 200 degrees Celsius.
S2-bearing ring is treated by high temperature tempering; working temperature can reach 250 degrees Celsius.
S3-bearing ring is treated by high temperature tempering; working temperature can reach 300 degrees Celsius.
The S4-bearing ring is treated by high temperature tempering; the working temperature can reach 350 degrees Celsius.
.10) Special skill condition F. . - consecutive numbering of production skill conditions. Example: F80-bearing; outer diameter public and radial clearance tightening.
K. . - consecutive numbered viewing skill conditions. Example: K5-bearing; outer diameter public service tightening.
. ZB - Cylindrical roller with a crown diameter greater than 80 mm. Example: NU364. ZB.
. The convexity of the two ends of the ZB2-needle is greater than the usual skill requirements. For example: K18*26*20F. ZB2.
ZW-Double-row needle roller and cage assembly. Example: K20*25*40FZW.
. 700... with 70000 initial consecutive numbered skill conditions.
Z52JN. 790144-bearings can be used for high temperature and low speed; special heat treatment; steel plate stamping riveting cage; large clearance; phosphating treatment; grease; operating temperature can exceed 270 degrees Celsius.
Z52JN. 790191-bearings can be used for high temperature and low speed; through special heat treatment; steel plate stamping riveting cage; large clearance; phosphating disposal; grease injection; operating temperature up to 270 degrees Celsius.
.11) Paired bearings 1) Paired bearings that meet K-skill conditions; the following special skill conditions are related to paired bearings:
K1-two sets of deep groove ball bearings are paired to accept one-way axial load.
K2-two sets of deep groove ball bearings are paired to accept bidirectional axial loads.
K3-two sets of deep groove ball bearings according to the backrest-free device (O-type device).
K4-two sets of deep groove ball bearings are equipped with no-gap face-to-face device (X-type device).
K6-two sets of angular touch ball bearings are paired to accept one-way axial load.
K7-two sets of angular touch ball bearings according to the backlash-free device (O-type device).
K8-two sets of angular touch ball bearings according to the no-gap face-to-face device (X-type device).
K9-in; two sets of tapered roller bearings with spacers between the outer rings are paired to accept one-way axial loads.
K10-inside; two sets of tapered roller bearings with spacers between the outer rings are back-to-back devices without backlash (O-type device).
Two sets of tapered roller bearings with spacers between K11 and outer ring are equipped with no-gap face-to-face device (X-type device).
2) Universal mating type bearing; optional (series; face-to-face or back-to-back) pairing device; post code UA; UO and UL.
. UA- has a small axial clearance when the bearings face to face or back to back.
. UO- no play when the bearing is face to face or back to back.
UL-light pre-interference when the bearing is face to face or back to back.
12) Smooth L. . - Smooth grease. Example: L64 = Arcanol brand saponification grease.
L9. . - Smooth oil.
.13) Packaging KS-metal plate container packaging.

We are very professional PE Tarpaulin manufacture since 1998. We can produce all the colors in tarpaulin line, such as blue, green, olive green, black, brown, orange, silver, camouflage, red, yellow, white, etc. Black PE Tarpaulin is one best selling item. As to the plastic tarpaulin have the features of tear-proof, water-proof, washable, anti-rot and UV-stabilized, so most of tarp sheet are used for covering, such as storage cover, utility cover, construction cover, outdoor and home covers, refugee tent, agricultural cover, temporary warehouse, canopy, irrigation dams, scaffolding covers, etc. Some customers even make one side black color, the other side different color for special usage, such as swimming pool.
Both of ready made sheet and in roll black PE tarp can be produced. Ready made sheet means the tarp sheet with reinforced pp rope inside four edges and aluminium eyelet every 3 feet or every 1 meter. In Roll Tarp means the Tarpaulin Fabric roll in the paper core directly
-
- Our black PE tarpaulin is usually with good quality, reasonable price and high quality service. The payment term is discussible. The delivery time can be guaranteed. if you have demand, welcome to contact us, we will always be there to support you
