"Black Diamond " brand cylinder liners being prepared for replacement by unit experienced and well established well known for quality producer in tractor, auto-marine and other spares since long time.
Technical Data :
| Material |
Material being selected of quality casted closed granuals inspected cast iron holding perfect hardness, machined, tensile strength and wear resistance also it is prepared with help of vanadium, Nickel, Molybdenum and chromium copper. |
| "Black Diamond" cylinders prepared for easy in fitment to run smooth engine for lowest fuel consumption, from standard specified graded cast iron composited with |
| TOTAL CARBON |
: 3 TO 3.3% |
| SULPHAR |
: 0.12% |
| PHOSPHOROUS |
: 0.3% |
| MANGANESE |
: 0.8 TO 1.2% |
| SILICON |
: 1.2 TO 1.6% |
|
| Microstructure |
Eutectic as bis specification uniform distribution of phosphate graffiti flakes paralytic structure with percentage of ferrite less than 5% is already. Black Diamond has achieved by quality control process to maintain micro structure. |
| Hardness |
Partially fully hardened and tempered cylinder (liners) are durable and works with recommended hardness 45 to 50 HRC minimum. |
| Tensile Strength |
Black Diamond is master to produce materials of cylinders with C.I.F.G. 200 minimum tensile strength at require stage. |
| Maintenance of Parallelism and flange square ness |
Parallel within 0.012MM flange faces remain generally lower flange faces at cylinder bore size of 150 indicate 0.05 while above bore size indicate 0.06 within mm. |
| Cylinder surface finishing |
Bore Size : 0.5 to 1.6 um
Outer Sealing (Machined) Max 5.7 um |
For profile of lubricants and wear resistance Black Diamond cylinders are honed as per international specification (hydraulically or diamond honed)
Black Diamond's cylinders are being manufacture for batter service to get perfect performance like, Genuine to give strength to weak spares of utilized vehicles on fitment engine can very smoothly.
