Would like to know if the following Crankset is compatible?
 

I am planning to replace my current crankset with a Shimano TOURNEY FC-TY501 6/7/8-speed Square Crank 48/38/28.



Would like to know if this compatible with my bike. Currently here's what I know about the specs:

Rear Cog: 32/11 (8 speed)

Rear Derailleur: Shimano Altus Rd- ct95 8 Speed

Front Derailleur: Shimano C050 Top Swing Sis

Crankset: SR Suntour PFF 42/32/22



Thank you for your help.

Maybe. The Tourney crank has significantly larger rings AKA "road" gearing vs "mtb" gearing. Your frame may not have clearance for the larger rings. To be safe you should replace like with like or take it to a shop for evaluation.

What's your chainline distance now? The FC-TY501 requires a D-NL (122mm) bottom bracket for a 47.5 mm chainline and a D-EL (127mm) for a 50mm chainline.
I suspect you'll need a new bottom bracket of the correct length as well.
This seems to suggest your existing crank uses a 113mm BB

i think it'll work, but the chain might be too short.
