XP/RA Rollers
RETURN ROLLERS
WITH SPACED RUBBER RINGS
CHARACTERISTICS
The characteristics of "XP/RA" return rollers with spaced rubber rings are identical to those of the "XP.20" basic roller in the various versions, i.e.:
- High load capacity.
- Hermetically sealed bearings thanks to a multiple labyrinth seal with cover plate.
- Standard rigid radial ball bearings with lifetime lubrication and oil-tight shields.
- Monobloc bearing shell turned and welded to the tube.
- Ground steel shaft.
- Availability with different tube lengths, shafts and in different versions.
APPLICATIONS
"XP/RA" return rollers with spaced rubber rings use D60 mm diameter "XP.20" units as the basic roller, fitted with D133 mm diameter rubber rings with narrow-tip tapered profile, spaced in such a way as to prevent material from adhering to the roller and causing its diameter to increase unevenly, with resulting belt tracking errors.
