KR	V	E	19	PP	SK	X	SS	RR
1	2	3	4	5	6	7	8	9
1. Cam followers series: KR
2. Roller guide: With cage – remove prefix “V”; Full complement roller – add prefix “V”
3. Stud adjustable: Centric – remove prefix “E”; Centric stud with eccentric collar – add prefix “E”; Eccentric stud – add prefix “H”
4. Roller size: this data is outside dimeter
5. Sealing type: Without plastic axial plain washers – remove suffix “PP”; With plastic axial plain washers – add suffix “PP”
6. Mounting hole: Hex socket – blank or suffix “SK”; Screwdrive slot – suffix “SL”
7. Profile outer ring: Crowned-blank; Cylindrica l- suffix “X”
8. Material: High Carbon chrome steel – blank; Stainless steel-suffix “SS”; Casehardened steel-suffix “CS”
9. Coating: Special corrosion resistance coating – add suffix “RR”; Oxide black surface finish – add suffix “B”

KR design cam followers, sizes 16 and 19

have a hexagonal recess in the head of the stud, enablling the stud to be held in place by a hexagonal key (Allen wrench) during mounting
have a relubrication hole with a pressed-in grease fitting (Accessories) in the centre of the hexagonal recess

KR design cam followers, sizes 22 and 26

have a hexagonal recess at each end of the stud, enabling the cam follower to be held in place by a hexagonal key (Allen wrench) during mounting
have a relubrication hole for a press-in grease fitting (Accessories) in the centre of each hexagonal recess:
- with the grease fitting already pressed-in at stud head side
- with the second grease fitting enclosed

KR design cam followers, sizes 30 to 90

have a hexagonal recess at each end of the stud, enabling the cam follower to be held in place by a hexagonal key (Allen wrench) during mounting
have a relubrication hole for a press-in grease fitting (Accessories) in the centre of each hexagonal recess:
- with the grease fitting already pressed-in at stud head side
- with the second grease fitting enclosed
have a relubrication hole in the stud seat

Features and Benefits

Features of KR series cam followers

a needle roller and cage assembly or a full complement needle roller set
have the outer ring axially guided by the pressed-on flange ring and the stud head (integral flange), forming a gap-type seal
have the stud head and stud thread black oxidized
are also available with with a PP contact seal (three-stage sealing by plastic axial plain washer) fitted on both sides
- protecting against coarse contaminants
- retaining grease reliably in the cam follower
- improving lubrication conditions in the cam follower, keeping friction and frictional heat low, and extending grease life
have a hexagonal recess at each end of the stud, enabling the cam follower to be held in place by a hexagonal key (Allen wrench) during mounting
have a relubrication hole for a press-in grease fitting or an adapter from a centralized lubrication system in the centre of each hexagonal recess (Accessories)
have a relubrication hole and an annular groove in the stud seat
accommodate relatively heavy axial loads that can occur because of skew or tilting

Benefits of KR series cam followers

High radial load carrying capacity
The thick-walled outer ring enables high radial loads, while reducing distortion and bending stresses.
Accommodate axial loads due to skew or tilting
The integral flange (stud head) and the pressed-on flange ring enable cam followers to accommodate axial loads that can occur because of skew or tilting.
Long service life
The crowned outer ring running surface is beneficial for applications where outer ring tilting relative to the track may occur or where edge stresses need to be minimized.
Easy to mount
The threaded solid stud (pin) of cam followers can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.
Sealed for increased reliability, with relubrication feature

Temperature limits

The permissible operating temperature for cam followers can be limited by:

the stud, the outer ring and rollers
the cage
the seals
the lubricant
the other components

When temperatures outside the permissible range, please contact us.

Stud, outer ring and rollers

Cam followers are heat stabilized up to at least:

140 °C (280 °F) for designs based on a cylindrical roller bearing
120 °C (250 °F) for designs based on a needle roller bearing

Cages

The permissible operating temperature for cages depends on the seal material:

steel cages can be used at the same operating temperature as the stud, the outer ring and rollers
120 °C (248 °F) for polyamide 66 cages

Seals

The permissible operating temperature for seals depends on the seal material:

NBR: –40 to +100 °C (–40 to +210 °F)
Temperatures up to 120 °C (250 °F) can be tolerated for brief periods
PP: –20 to +80 °C (–5 to +185 °F)
PTFE: -196 to +260 °C (–320 to +500°F) * continuous working temperature had better below +200 °C ( +392°F)
Sheet metal angle rings can be used at the same operating temperatures as the stud, the outer rings and rollers

Lubricants

Lithium Soap Grease NLGI #2

SINOPEC Hangu 2# : –20 to +120 °C (–4 to +248 °F)
Shell Alvania EP2: –20 to +120 °C (–4 to +248 °F)

Other components

Eccentric collars and pressed-on flange rings can be used at the same operating temperature as the stud, the outer ring and rollers.
