MZE Black PU-Coated Geared Rollers, 35 mm OD, 70–140 mm Long
MZE Black PU-Coated Geared Rollers, 35 mm Contact Diameter
These rollers combine two black polyurethane contact pads, a central metal spur gear and two 6801ZZ bearings. The source drawings specify a 6061 aluminum core. They are components for a compatible mechanical feeding, conveying or synchronized roller arrangement; select the gear mesh and shaft support for the actual machine.
Understand the Model Before Ordering
In MZE-35×W-6801-L, 35 is the coated outside diameter, W is the width of each of the two contact pads, 6801 is the bearing reference and L is the overall assembly length. W is not the full roller length. The listed combinations use L = 2W + 40 mm; the original drawing separately shows the central gear and relief sections.

Millimetres are the ordering dimensions. Inches use 25.4 mm per inch, rounded to three decimals. Review the exact original drawing image for all steps, bearing seats and tolerances rather than using only the model code.
Construction and Gear Parameters
| Item | Source drawing specification |
|---|---|
| Contact pads | Two black polyurethane pads, 35 mm OD /1.378 in. |
| Hardness | Drawing reference 75; the hardness scale is not identified. Confirm the required scale before specifying hardness-critical use. |
| Core | 6061 aluminum, as stated on the model drawings. |
| Bearings | 2 x 6801ZZ; 12 mm /0.472 in nominal inner bore. |
| Spur gear | Module 1.5, 17 teeth, 20° pressure angle. |
| Gear pitch diameter | 25.5 mm /1.004 in. |
| Gear outside / root diameter | Original drawing callouts: 28.5 mm /1.122 in and 21.75 mm /0.856 in. |
| Gear face width | 20 mm /0.787 in central dimension in the drawing. |
| Quantity and scope | One selected roller assembly. Shaft, mating gear, drive motor, frame, guards and other machine parts are not specified as included. |
What the Roller Is Used For
| Application to evaluate | Role of the component | Match before ordering |
|---|---|---|
| Gear-coupled feed mechanism | A mating gear can transmit rotation while the two PU pads contact the workpiece. | Module, tooth count, pressure angle, center distance, backlash, rotation direction and usable face width. |
| Synchronized conveying or guiding | Provides two separated contact surfaces and a central geared interface. | Required surface speed, pad spacing, alignment, contact force and workpiece condition. |
| Replacement roller in machinery | Replaces a component with matching dimensions and bearing arrangement. | Overall length, pad width, bearing fit, shaft retention and clearances from the original drawing. |
The supplied images are CAD illustrations and engineering drawings. No installed-machine application photograph is supplied. Load capacity, rated torque, speed limit, runout, noise reduction, service temperature and lifetime are not established by this material; select the assembly for the actual duty and environment.
Installation and Inspection
- Confirm both pad widths, overall length, 12 mm bearing bore and exact mating gear geometry.
- Use suitable shaft support, spacers and axial retention. Protect the PU contact surfaces and load the correct bearing ring during assembly.
- Align the gear mesh and check controlled backlash, contact pattern, free rotation and pad tracking before applying working load.
- Guard moving gears and test at controlled speed. Inspect bearing heat, vibration, wear and workpiece marking. Isolate the machine before adjustment.
Custom Configurations
For other dimensions, materials or a shaft assembly, send a dimensioned drawing, mating-gear data, quantity, working load, speed and environment to boltte@boltte.com. Confirm the finished configuration and supply scope before ordering; a consultation amount is not a configured custom-product offer.
Original Product, Drawing and Application Images
Original product geometry and dimension lines are retained. The source illustrations show the central gear, two contact pads, bearing openings and family layouts. Each listed model has its own translated original drawing in the upper gallery and below.
