1.The poly-vee pulley is located at the end of the roller which separates the
drive area and the conveying area making the conveying smooth, high
speed and low noise.
2.The bearing end cap consists of a precision ball bearing, a polymer housing
and end cap seal. Combined they provide an attractive, smooth and quite
3.The design of the end cap protects the bearings by providing excellent
resistance to dust and splashed water.
4.PJ series poly-vee. Total of 9 grooves at 2.34mm pitch.
5.Various PJ belt lengths available to suit different pitch of rollers.
6.Suitable for the high speed applications. Maximum speed varies with roller
length and diameter. Maximum speed up to 2~3m/s.
7.Standard configuration with anti-static design surface impedance≤106Ω。
8.Temperature range: -5℃ ~ +40℃.
9.Humidity range: 30-90% RH (non-condensation).
Please contact us if humidity out of this scope.
Remark: Φ50 rollers can be fitted with PVC sleeve (2mm) and PU sleeve (2mm).
11hex can provide tapered plastic steel shaft sleeve roller.
Please choose the steel Poly-Vee roller when you must use 4PJ belt.
Polymer noiseless sleeve for shaft roller：
① Actual frame width= E+（1~3）mm，Excessive width inside the frame will damage the shaft core and roller.
② Applicable mounting hole range：11.2~11.7mm（edge to edge）.
