Conveyor rollers

Buy Conveyor Rollers at Zavod Moroza

Conveyor rollers are the main rotating units of a belt conveyor, designed to support the belt (both carrying and return strands) and provide it with the necessary profile (flat, trough, or V-shaped). It is the conveyor rollers that take on the entire weight load from the material being moved and ensure the smooth movement of the main line.

Although structurally a roller looks like a simple support, the stability of the entire line and the service life of the conveyor belt - one of the most expensive consumable parts of the conveyor - directly depend on the quality of its execution. For example, a violation of geometry (radial runout) causes vibration and "jumping" of the belt, which inevitably leads to product spillage and damage to mounting seats. In turn, bearing seizure turns the roller into a stationary obstacle that intensely scrubs the rubber-fabric web, creates excessive resistance for the motor, and in conditions of a dusty elevator - provokes dangerous local overheating.

Understanding these operational challenges, Zavod Moroza ensures industrial assembly quality, where the priority is the tightness of the bearing unit and the precise geometry of the product. We specialize in manufacturing reliable components of both standard types (plain rollers) and special purposes - impact rollers (lined with rubber rings to soften blows) and guide rollers (for belt centering). The production process is not limited to warehouse templates - we design units for specific customer conditions, adapting the length, diameter, type of sealing, and shaft fastening method.

Design Features of Our Conveyor Rollers

A critically important factor in the durability of a conveyor roller is the protection of the bearing unit from the external environment. In our products, we use reliable cast bearing housings (cast iron or steel), which are securely fixed in the tube. To prevent abrasive grain dust and moisture from getting into the grease, we apply a multi-stage protection system - we install closed-type bearings and, if necessary, additional labyrinth seals. This eliminates the risk of caking and mechanism seizure even when working in dusty elevator premises or on open threshing floors.

We pay special attention specifically to the geometry of our conveyor rollers. To avoid vibrations and premature wear, the connection of the housing to the tube (shell) is performed on centering equipment - this ensures high coaxiality and minimal radial runout of the roller during operation. Thanks to this, the belt moves smoothly, without jerks and vertical oscillations, which guarantees the preservation of grain or other bulk materials from spillage.

The roller shaft is made of quality calibrated steel (St 20, St 35, St 45) and depending on the design of your conveyor, we offer different options for shaft end machining:

• with flats (milled "for a wrench") - the most common option for quick drop-in mounting into frame slots without using tools.
• with internal thread - for rigid fixation of the roller to the frame using bolts.

Such variability of shaft execution, combined with a sealed housing and precise centering, makes our rollers a universal repair solution - you receive a unit that is fully ready for installation and fits perfectly into the mounting seats of your equipment, requiring no additional locksmith work "on site".

Manufacturing of Any Rollers for Conveyor Belts

Since the width of conveyor belts and frame designs from different manufacturers can vary significantly, we do not limit you only to standard warehouse positions. The production capacities of Zavod Moroza allow us to quickly manufacture a batch of rollers of any volume according to your individual drawings or samples.

Technical production capabilities:

• Shell diameter (tube) - we manufacture the entire spectrum of standard sizes (57, 76, 89, 102, 108, 127, 159 mm + non-standard)
• Roller length - from 200 mm to 2000 mm and more (with cutting accuracy up to 1 mm for your frame)
• Anti-corrosion protection - all products undergo a priming (or painting) stage, which ensures a marketable appearance and metal protection against corrosion during transportation and warehouse storage

To launch a batch into production, we only need to know the basic geometric parameters (tube diameter, total length, and shaft end type). Contact our sales department to get a technical consultation, calculate the exact cost of the order, and agree on shipping terms.
