The first shaft head 12 and the second shaft head 13 are also secured to the roller body 11 via a plurality of saddle pins to prevent relative rotation.

[0028] The first bearing assembly 2 and the second bearing assembly 3 are mounted on the housing assembly 4 in a front-to-back relationship, and the friction roller 1 is mounted on the housing assembly 4 so as to be rotatable about its own axis X1. The housing assembly 4 includes a first support seat 41, a second support seat 42, and a connecting profile 43 connected between the first support seat 41 and the second support seat 42.

Three separation-type ring grooves are formed between the outer wall surface of the second bearing sleeve 31 and the inner wall surface of the second support seat 42. Each separation-type ring groove is configured to accommodate a second O-ring 33. The depth of each separation-type ring groove is less than the diameter of the second O-ring 33, so that the second O-ring 33 can be sealed between the second support seat 42 and the second bearing sleeve 31.

[0035] The second bearing sleeve 31 adopts a split structure. The second bearing sleeve 31 includes a semicircular first part and a second part. The first part and the second part are arranged opposite to each other in the upper and lower parts.

The upper support plate 53 and the lower support plate 54 are fixedly mounted on the square tube 51 in an upward and downward direction, and each copper ball guide post 52 is connected between the upper support plate 53 and the lower support plate 54. The support assembly 5 allows the box assembly 4 to be supported on the operating device by hanging on its side to prevent the operating device from tipping forward due to the excessive weight of the friction roller device 100.

[0037] The friction roller of the present application is arranged on a side-mounted box assembly, which reduces the overturning moment of the friction roller device and enables the friction roller to operate quietly and smoothly.

[0038] The above shows and describes the basic principles, main features and advantages of the present application.
