Timber Conveyor Chain Manufacturer for Wood Material Handling
Timber conveyor chain is designed for conveying wood products and timber materials in industrial handling systems. Its roller chain structure supports stable material transfer and can be selected according to pitch, chain width, pin dimensions, plate thickness, breaking load, and equipment requirements.
The supplied technical information covers three ANSI models: 81X, 81XH, and 81XHH. The technical drawing shows the chain structure, roller arrangement, pin dimensions, plate thickness, and main installation dimensions.
As a professional industrial chain manufacturer with decades of production experience, we supply timber conveyor chains to customers worldwide. OEM, ODM, and sample services are available for sawmill equipment manufacturers, timber-processing machinery companies, conveyor integrators, distributors, and maintenance providers.
Timber Conveyor Chain Structure
Roller Chain Construction
The timber conveyor chain consists of inner and outer plates, rollers, pins, and connecting components. The chain dimensions should be matched with compatible sprockets and the complete conveyor structure.
Chain Plate Design
The chain plate structure is suitable for conveying equipment that requires stable chain guidance and continuous material movement. Different plate thickness configurations are available within the listed 81X, 81XH, and 81XHH models.
Technical Drawing Dimensions
The supplied drawing includes the following dimensions:
Pitch P
Plate height h
Width between inner plates b1
Pin diameter d2
Pin length b2
Inner plate thickness T1
Outer plate thickness T2
Roller diameter d1
Final dimensions should be confirmed against the approved equipment drawing and operating requirements.
81X, 81XH, and 81XHH Timber Conveyor Chain Models
81X
The 81X model is listed with a pitch of 66.27 mm, roller diameter of 23.02 mm, and width between inner plates of 26.99 mm. Its listed breaking load is 106.7 kN, with a weight of 3.90 kg/m.
81XH
The 81XH model has the same listed pitch, roller diameter, and inner plate width as 81X, with different pin length and plate thickness values. Its listed breaking load is 152.0 kN, with a weight of 5.90 kg/m.
81XHH
The 81XHH model uses the same listed pitch, roller diameter, and inner plate width as the other two models. It provides a listed breaking load of 186.7 kN, with a weight of 6.52 kg/m.
The appropriate model should be selected according to conveyor load, equipment structure, operating cycle, sprocket compatibility, and required plate configuration.

Timber Conveyor Chain Features
Stable Material Transfer
The chain is designed for continuous conveying systems used to transfer timber and wood-related materials. Correct sprocket engagement, alignment, tension, and lubrication help support stable operation.
Three Model Options
The 81X, 81XH, and 81XHH models provide different pin length and plate thickness configurations while sharing the listed pitch, roller diameter, and inner plate width.
Technical Parameter-Based Selection
The supplied table allows equipment designers to compare chain dimensions, plate configuration, breaking load, and weight per meter before selecting a model.
Suitable for Conveyor Integration
The chain can be evaluated for new conveyor equipment, replacement projects, and customized timber-handling machinery according to confirmed technical requirements.

Conveyor Maintenance and Replacement
The 81X, 81XH, and 81XHH models can be evaluated for replacement or maintenance applications when the original chain dimensions, sprocket specifications, and operating conditions are confirmed.
The final application should be assessed according to material weight, conveying speed, conveyor length, impact conditions, moisture, dust, lubrication, and operating cycle.
Timber Conveyor Chain Selection Guide
Confirm the Chain Model
Select 81X, 81XH, or 81XHH according to the required plate configuration, pin length, breaking load reference, equipment structure, and replacement requirements.
Check the Pitch and Sprocket
The listed pitch is 66.27 mm for all three models. The sprocket and chain path should be confirmed to ensure compatibility with the selected chain.
Check Plate Thickness
The listed inner and outer plate thicknesses differ between the models. Confirm the required T1 and T2 values against the conveyor design and original chain specification.
Check Working Conditions
The listed breaking load is reference data and should not be treated as the allowable working load. Actual selection should consider working load, impact, speed, safety factor, lubrication, and operating environment.
Confirm Complete Dimensions
Please compare the pitch, roller diameter, inner plate width, pin diameter, pin length, plate height, and plate thickness with the approved equipment drawing before production.
