| outline structure fixed disc type free side packing outer race inner race boot shaft flanged hub cage balls boot retainer plate grease nipple features greater allowable operating angle though varying depending on the cvj size and intended rpm the maximum allowable operating angle of this type of joint is 18° with boot remarks 1 if the maximum allowable operating angle is exceeded use a cup type joint 2 if this type of application is unavoidable use a sliding type joint or combine a fixed disc type joint with a slide type joint for types and their combination contact ntn engineering 3 the disc type ... | |
| outline fixed cup type free side outer race inner race boot band boot band cage ball booth shaft features remarks greater allowable operating angle the maximum allowable operating angle with the cvj proper is 42° though varying depending on the intended rpm the maximum allowable operating angle of the joint equipped with a boot is 25° at dynamic state and 38° at static state 1 this type is not suitable for use under a situation where an expansion motion occurs while the joint is revolving if this type of application is unavoidable use a sliding type joint or combine a fixed cup type joint with ... | |
| outline sliding type outer race o-ring cage inner race boot band square-section circlip boot band c-ring ball round-section circlip boot shaft features expansion is possible within cvj the ball tracks on the outer race are parallel with the axis therefore relative axial expansion between the inner ring and outer ring is possible while transmitting power and providing an operating angle remarks 1 for the best operation of a sliding type joint the operating angleexpansion correlation operating method and installation/removal method should be considered for details contact ntn engineering 2 if much ... | |
| outline coupling type short shaft series outer race cage square-section circlip inner race round-section circlip shaft o-ring flanged hub ball c-ring boot boot band hexagon nut spring hexagon washer headed bolt long shaft series outer race inner race square-section circlip boot band boot band cage c-ring ball round-section circlip boot shaft features no alignment work is necessary the offset across both shafts when the coupling is installed is 3.5 to 11.5 mm in the case of short shaft series joints see fig 1 the long shaft series joints offer much larger offset see fig 3 the maximum crossed angle ... | |
| usage and handling step 5 mount the cvj assembly onto the shaft until the inner race is against the square section circlip and lock it with a c-ring photo 25 caution handle the c-ring with care the spring force in the ring can cause it to fly off if it slips during installation c-ring photo 25 step 6 inject ntn provided authorized grease into the mounting portion on the cvj assembly photo 26 photo 26 step 7 fit the boot into the boot retaining grooves on the shaft and outer race fit the boot bands over the boot and fasten them 1 photo 27 1 for fastening the boot bands see sec 4.6 and 4.7 on page ... | |
