What Are the Key Features of 131.40.1600 Slewing Bearing for Industrial Applications?
The 131.40.1600 Slewing Bearing is part of the 131 series three-row cylindrical roller family. It is designed for the heaviest load needs of all the slewing bearing types. To do this effectively, the forces are distributed to three different raceways. The vertical row will carry radial loads, and the horizontal rollers will bear axial loads and overturning moments. This separation avoids cross-loading stress and enables each roller set to work at the optimum contact geometry.
The 131.40.1600 is an external gear slewing ring with driving teeth directly on the outer ring, allowing easy connection to a pinion-driven motor. This removes unnecessary gearbox components, shortens the drive chain, and simplifies installation and periodic maintenance. The gear is machined to module 14 with 131 teeth, giving a tip diameter of 1873.2 mm and a tooth width of 150 mm – sizes that allow reliable torque transfer under strong cyclic loads.
| Feature | Detail |
|---|---|
| Structure Type | Three-row cylindrical roller (131 series) |
| Load Capacity | Axial, radial, and overturning moment simultaneously |
| Gear Configuration | External gear, Module M14, Z=131 |
| Raceway Design | Separate horizontal and vertical roller paths |
| Sealing | Nitrile rubber (NBR) or fluororubber (FKM) |
| Typical Applications | Cranes, port equipment, mining, metallurgical machinery |
The hardened raceways — typically surface-quenched to HRC 55–62 — resist surface fatigue even under continuous heavy loading, which directly extends service life and reduces unplanned downtime.

These numbers are why 131.40.1600 is so reliable in harsh surroundings. The 48 mounting holes in two bolt rings give a secure, equally loaded interface to the machine frame. Six grease nipples make sure that all three raceways are sufficiently lubricated, which is important for bearings of this diameter. The gear circumferential force is found to be 263 kN for the normalised state and 366 kN for the quenched and tempered condition, confirming the capability of the gear to transfer large torque without tooth deformation or premature wear.
How to Choose the Right 131.40.1600 Slewing Bearing OEM Manufacturer?
The choice of the correct provider is just as important as the choice of the proper bearing model. A certified OEM slewing bearing manufacturer should manage in-house each manufacturing step from forging and rough machining to heat treatment, gear hobbing, grinding, and final assembly. For partner assessment, ask for material certificates (chemical composition and mechanical qualities), heat treatment records (including raceway hardness depth charts), and dimensional inspection reports for each batch.
| Evaluation Criterion | What to Verify |
|---|---|
| Material Certification | 42CrMo / 50Mn composition and hardness reports |
| Heat Treatment | Raceway surface hardness HRC 55–62, effective case depth |
| Gear Quality | Tooth profile accuracy, pitch error, runout inspection |
| Dimensional Inspection | Bore, OD, height, mounting hole positions |
| Sealing Integrity | Seal fit, grease retention, contamination resistance |
| After-Sales Support | Technical consultation, warranty terms, spare availability |

Custom Design, Material Selection, and Quality Control for 131.40.1600 Slewing Bearing
Every project imposes unique constraints — from available mounting space to environmental aggressors like dust, salt spray, or chemical exposure. That is why custom engineering plays a central role in our manufacturing process. Our team adjusts bore diameter, gear parameters (module, tooth count, pressure angle), mounting hole patterns, and sealing type for each 131.40.1600 Slewing Bearing order. Depending on the load profile and operating environment, we may recommend 42CrMo for high-stress applications, 50Mn for standard-duty service, or alternative alloy steels with specialized heat treatment for extreme conditions.
| Quality Control Stage | Key Focus |
|---|---|
| Raw Material Inspection | Chemical composition, tensile strength, hardness |
| Rough Machining | Dimensional accuracy, roundness, surface finish |
| Heat Treatment | Raceway hardness depth, gear tooth hardness |
| Finish Machining | Gear profile accuracy, mounting hole positions |
| Final Testing | Rotation torque, noise level, seal integrity |
This structured process ensures every 131.40.1600 Slewing Bearing leaving our Luoyang facility meets strict tolerance standards. Each bearing undergoes rotational testing under loaded conditions before packaging, and full inspection documentation accompanies every shipment.
Why OEM Custom Solutions Matter for 131.40.1600 Slewing Bearing Projects?
Off-the-shelf bearings rarely match every application perfectly. A bearing that is slightly too tall, has the wrong gear module, or lacks the correct seal material can force costly machine redesigns or accelerate wear. As an experienced OEM slewing bearing manufacturer, Heng Guan Bearing helps customers avoid these compromises by tailoring the 131.40.1600 to the exact machine interface — matching gear specifications to the existing pinion, adjusting mounting hole patterns to the existing bolt circle, and selecting seal materials suited to the operating environment.
Custom solutions often reduce total system cost over the equipment's life cycle. Better load distribution extends bearing life, correct gear meshing reduces pinion wear, and appropriate sealing prevents premature failure from contamination. Whether you are upgrading an existing crane or designing new equipment, consulting our engineering team early in the design phase allows us to integrate the right bearing solution from the start — avoiding costly retrofits and field modifications later.
