| Bearing play |
| The radial play of NBHY bearings might bedivided into five groups accor ding to ISO 5753.The radial play without pre-load is shown on the table.Normally.the products are asswmbled as basic group play.Please nite the spcial requirement in you order sheet if any customer needsbearing play rather than the value of basic qroup. |

| Dustproof,sealing and lubrication |
| The stru cture of bearings consist of open and close types,and the close rype might be equipped with dust proof on single side or both sides (Z,Z,Z); with non-oontact se aling ring on single side or both sides(RS,2RS),and with contact sealing ring on single side or both sides(RS,2RS). Before ex works,the product is filled properly withlubricant oil and grease. You ay use it imm ediately after unpacking and cleaning is unnecessary. It is suitable for light to middle load, lowto middle speed and working temperature-20'C.F or and special case, please note the usage and brand of grease on your order. |
| The common brand and performance of grease id shown on table. |

| Bearing accuracy |
| Bearing accuracy refer sto accuracy on dimension and rotation. According to Chinese national standard,the bearing accu-racyis divided into five classes;class0,class6,class5,class4,and class2.All of them are equivalent to ISO standard. The comparison of different accuracy classes are shoen as follows: |
| Comparison Table of Accuracy Grade |
| tandard code name | Accuracy Grade | | GB | 0 | 6 | 5 | 4 | 2 | | ISO | 0 | 6 | 5 | 4 | 2 | | ANSI | ABE C1 | ABE C3 | ABE C5 | ABE C7 | ABE C9 | | SKF | PO | P6 | P5 | P4 | P2 | | DIN | PO | P6 | P5 | P4 | P2 | | JIS | 0 | 6 | 5 | 4 | 2 |

| Bearing collar and roller material |
| The bestm aterial for rolling bearing is high carbon chromium be aring steel.which features desired hardness, strong rolling fatigue resistance,wearing gresitance and stable dimension, Its chemical composition is: |
| chemical composition of Bearing steel Gcr15 |

|
| Bearing vibration noise specification |
| Accor ding to related standard,the vibration noise(dB)of NBHY bearings for rheir cilbr ation under accelerarion are dicided into four groups:Z1,Z2,Z3,Z4.Also they can be civided into four groups in according to vibration speed(μm/s):V1,V2,V3,V4,Nor mally, comm on bearings are dlicered wit Z1 group vibration value ifno special requirement from customers while the be arings for export will be delicered with cibration Z2 group specification.Hoevwer, please note your special requirem ent on vibration in your Order. |
