Example 1 When the inner ring has 4 oil holesCRBC 10020 / 4OH C14 Oil holes In inner ringExample 2 When the outer ring has a single oil holeCRBC 10020 - OH C11 Oil hole In outer ring■Operating Temperature Rangewhile considering the dimension of bearing width which is given a minus tolerance. (See Fig.2)●2 The depth of the housing bore is recommended to be equal to or larger than the bearing width.●3 Separation prevention bolts for the outer ring of Standard Type Crossed Roller Bearings are provided to prevent separation of two halves of the outer ring during transportation or mounting. When mounting, they should be loosened slightly.●4 High Rigidity Type Crossed Roller Bearings V, Super Slim Type Crossed Roller Bearings and Slim Type Crossed Roller Bearings have a plug for hole for inserting rollers. When mounting the bearings, locate the plug at a position that is not included in the maxi-mum loading zone. The plug location can be found by The operating temperature range is -25 to 120°C for the pin pressed at the side of the outer ring.Lightweight Crossed Roller Bearings, and -20 to 120°C for the other Crossed Roller Bearings. However, the maxi-mum allowable temperature for types with separator and 2. ounting Holed Type High Rigidity Crossed Roller Bearings V, Mounting Holed Type Super Slim Crossed with seal is+110℃, and+100℃ when they are continu-Roller Bearings, and Lightweight Crossed Roller Bearingsously operated.■MountingWhen the rigidity of the mounting parts is not suffi-cient, stress concentration will occur at the contact area between the rollers and raceways, and the bear-ing performance will be deteriorated signicantly.Therefore, it is necessary to carefully examine the rigidity of housing and the strength of fixing bolts when a large moment will be applied.The shoulder height diameters (da and Da) that are related to mounting should certainly satisfy the values shown in the dimension tables. When these dimen-sions are incorrect, deformations of inner and outer rings will occur and the bearing performance will be deteriorated remarkably.1. Other than Mounting Holed Type Crossed Roller BearingsFig. 2 Mounting example●1 The inner and outer rings should be securely xed fixing plates, etc. in the axial direction by using Recommended thickness of the xing plate is 1/2 or more of the bearing width B. The dimensions in the fixing axial direction of the housing bore and the Fig. 3 Example of direct mounting to the mating surface of Mounting Holed Type High Rigidity Crossed Roller Bearings VFig. 4 Example of direct mounting to the mating surface of Mounting Holed Type Super Slim Crossed Roller BearingsFig. 5 Example of mounting to the housing of Mounting Holed Type High Rigidity Crossed Roller Bearings V●1 Inner and outer rings can be mounted directly to the mounting surface with xing bolts. (See Fig. 3, and Fig. 4)●2 A housing should be used when positioning accuracy is is required, or when high radial load or moment applied to Mounting Holed Type High Rigidity Crossed Roller Bearings V or Mounting Holed Type Super Slim Crossed Roller Bearings. (See Fig. 5)●3 Mounting Holed Type High Rigidity Crossed Roller Bearings V, Mounting Holed Type Super Slim Crossed Roller Bearings have a plug for hole for inserting cylin-drical rollers. When mounting the bearings, locate the plates should be determined to get a secure fixing plug at a position that is not included in the maximum J13loading zone. The plug location can be found by the pin pressed at the side of the outer ring.
