Description
MC112 is a versatile hollow pin conveyor chain family with multiple pitch choices and roller arrangements. It is designed for conveyors that use the hollow pin as a mounting point for cross rods, product carriers, spacers, guides, pushers or customized fixtures.

Best suited to
MC112 can be considered for packaging, assembly automation, food handling and general conveyor systems that need cross rods, carriers or custom fixtures. MC series is a good starting point when the conveyor designer needs flexibility in pitch and roller geometry. The final choice should also match the sprocket, guide rail, attachment layout, conveyor speed, product load and environment.
Attachment possibilities
The through-bore can be used with rods, bolts, spacers and custom carrier hardware. When an attachment connects two parallel chains, provide the chain center distance, cross-member diameter, span and load position. For single-strand attachments, show the side clearance and retaining method so the hardware can pass through guides and around the sprocket without interference.
Cross rods
Connect two strands for slats, carriers and product supports.
Pushers & fixtures
Create repeatable attachment points for indexing and product positioning.
Removable hardware
Use bolts, collars, spacers or other serviceable retaining concepts around the hollow bore.
How to choose MC112
- Confirm the pitch and sprocket tooth geometry.
- Compare hollow bore with the proposed rod or attachment diameter.
- Check inner width, roller/bush diameter and plate envelope against the guides.
- Check overall pin projection against side-frame and transfer clearances.
- State conveyor speed, operating load, starts/stops and any shock or jam conditions.
- State moisture, washdown, dust, temperature and lubrication requirements.
Replacement matching
If MC112 is being considered as a replacement, measure several pitches under light tension and record the hollow bore, inner width, roller or bush diameter and overall pin length. Add the sprocket tooth count and clear photos of the chain in the guide and around the drive sprocket. These checks help avoid a dimensional match that still conflicts with the existing machine.
Maintenance
Keep sprockets aligned and inspect tooth wear when replacing chain. Monitor chain elongation over a fixed number of pitches, look for stiff joints, check hollow bores and inserted rods for fretting or looseness, and inspect guides for uneven contact. Where lubrication is permitted, apply a suitable lubricant to the articulating joint rather than only the outside plates.

How to evaluate MC112 in your conveyor
MC112 should be selected as part of the complete conveyor interface, not from the model number alone. The listed pitch options are 100 / 125 / 160 / 200 / 250 / 315 mm, with a minimum hollow bore of 14.3 mm and an inner width of 32.0 mm. Use these dimensions to compare the chain with the sprocket, guide rail and attachment drawing. If the chain is replacing an installed part, measure several pitches under light tension and compare the worn sample with the machine documentation before approving an interchange.
MC112 within the MC Series
The MC family is useful when a buyer needs a general hollow-pin conveyor-chain platform with several pitch choices and roller arrangements. For MC112, the listed roller diameter is 70.0 mm and the minimum tensile-strength reference is 112.0 kN. Treat that tensile figure as a catalogue strength value rather than an allowable working load; the operating load still depends on conveyor geometry, speed, shock, lubrication and service conditions. When comparing MC112 with another MC size, focus on bore, inner width, roller diameter and plate envelope as well as nominal strength.
Attachment and cross-rod checks
The hollow pin provides a mounting path for rods, spacers, product carriers or custom fixtures, but the attachment becomes part of the load path. State rod diameter, rod material, retention method and the distance between chain strands. For a wide two-strand conveyor, include the unsupported rod span and product or fixture load so bending and side load can be reviewed. If the attachment is removed during product changeover or sanitation, show the outside retention hardware and confirm tool access around the chain.
Sprocket, guide and maintenance compatibility
Pitch is only one part of interchange. Confirm roller or bush diameter, inner width, side-plate envelope and overall pin projection against the existing sprocket and guide. A new chain should not be installed on badly hooked sprocket teeth or a guide rail that forces the chain sideways. After installation, run the conveyor slowly without product, watch the chain through the sprockets and guides, then recheck tension and attachment hardware after the first operating period.
