Product Details

Stud Type Track Rollers are precision-engineered rolling elements designed to support high radial loads while ensuring smooth and reliable motion along tracks, guide rails, and cam mechanisms. Featuring a robust stud shaft, thick-walled outer ring, and high-quality bearing components, they provide excellent wear resistance, durability, and operational stability. Available in sealed and shielded configurations, they offer effective protection against dust, moisture, and contaminants. These rollers are widely used in automation equipment, material handling systems, packaging machinery, conveyors, machine tools, and industrial applications requiring accurate guidance and long service life. Custom designs and surface treatments are available to meet specific operating requirements.

When To Choose This Structure — Slewing Bearing

Sheet 01 · Selection Guide

When Should I Choose This Structure?

Before you place an order, check whether a triple-row roller slewing bearing actually matches your equipment’s duty conditions — faster than reading any spec sheet.

Your equipment needs continuous 360° rotation under high torque, heavy-load conditions — e.g. cranes, excavators, tunnel boring machines, wind turbine yaw systems.
Installation space is limited, and axial load, radial load and tilting moment must be carried by a single bearing rather than a separate bearing-plus-gearbox assembly.
The equipment needs a built-in slewing drive gear (internal or external), eliminating extra transmission components and simplifying assembly.
The operating environment involves dust, moisture, or large temperature swings, requiring a bearing with built-in sealing and lubrication channels.
The project has clear requirements for rotational accuracy and adjustable clearance — e.g. medical equipment, solar tracking mounts, precision turntables.

One-line summary

If your equipment needs to “rotate and carry heavy loads at the same time,” a triple-row roller slewing bearing is usually the most direct, integrated solution.

Typical equipment

Tower crane slewing platforms, crawler crane turntables, excavator upper structures, TBM cutterhead drives, wind turbine yaw/pitch systems, stacker-reclaimer slewing bodies.

When NOT To Choose It — Slewing Bearing

Sheet 02 · When Not To Use

When Should I NOT Choose It?

We’d rather help you find the right solution than sell you the wrong one. Here’s when a slewing bearing may not be the best fit.

If your rotational speed requirement exceeds the typical design range for slewing bearings (e.g. high-speed rotating platforms), a cross roller bearing or dedicated high-speed structure is usually a better fit.
If overall weight is extremely sensitive for the machine (e.g. drone gimbals, small precision instruments), a thin-section or angular-contact bearing combination may be lighter and more suitable.
If budget and production volume favor a standard bearing plus external gear assembly, that may be more cost-effective for non-heavy-duty, non-harsh-environment applications.
If installation space is extremely constrained and cannot meet the minimum installation diameter, confirm with our engineers whether a compact custom design is available.

Not sure which case applies to you?

Send us your equipment’s duty conditions (load / speed / space / environment) and our engineers will tell you within 24 hours whether it fits — not just try to sell you something.

Required Data For Selection — Slewing Bearing

Sheet 03 · Selection Data

Required Data For Selection

You don’t need a finished drawing to get started — tell us what you already know, and our engineers will help fill in the rest.

Category	Data Needed	Why It Matters
Load Parameters	Axial load, radial load, tilting moment	Determines the number of rows and raceway design
Envelope Dimensions	Installation OD / ID, installation height, bolt hole pattern	Determines whether a standard size fits or custom sizing is needed
Speed & Duty	Operating speed (rpm), continuous or intermittent duty, environment	Affects lubrication method and seal grade
Drive Type	Internal-tooth / external-tooth / no gear (bearing only)	Determines gear module, tooth count and precision grade
Precision	Rotational accuracy, clearance range (negative clearance required?)	Affects manufacturing process and inspection standard
Drawing / Reference Part	Existing drawing, old bearing model, or competitor part number	Allows a direct 1:1 match or replication — the fastest path to selection

No drawing on hand? That’s fine — send us the parameters you know, or a photo of your old bearing’s nameplate.

Materials, Hardness, Clearance & Gear — Slewing Bearing

Sheet 05 · Material & Process

Materials / Hardness / Clearance / Gear Treatment

Every batch ships with a material certificate, hardness test report and NDT report — third-party re-inspection is welcome.

01 · MATERIAL

Ring Material

42CrMo / 50Mn (specifiable)

Determines overall strength and fatigue life. Heavy-duty applications use alloy structural steel with quenching & tempering.

02 · HARDNESS

Raceway Hardness

HRC 55–62, depth customizable

Medium-frequency induction hardening gives more uniform hardness than through-hardening, avoiding soft spots.

03 · CLEARANCE

Clearance Grade

Standard or negative, P0–P6

Heavy-duty, low-speed equipment usually uses negative clearance for higher stiffness; precision equipment can go tighter.

04 · GEAR

Gear Treatment

Q&T or induction-hardened teeth

Frequent start/stop or heavy-duty drive applications benefit from hardened tooth flanks for longer life.

Custom triple-row roller slewing bearing manufactured for a stacker-reclaimer, Southeast Asia port project

Case File · Port Machinery

Stacker-Reclaimer Slewing Bearing — Custom Project, SE Asia

Background: The customer was using an imported triple-row roller slewing bearing with a 4-month lead time and a high price point.
Requirement: Find a faster-to-deliver alternative while keeping the original installation dimensions and load parameters unchanged.
Solution: Based on the customer’s original part drawing, we replicated the key dimensions and gear geometry 1:1, and raised raceway hardness to HRC 58–62.
